Release v1.21.0 (#1348)

This will ensure the ParentID is *not* set when the message refers to a
message that was sent in a different channel.

+# v1.21.0
+
+## Breaking Changes
+
+- discord: Remove WebhookURL support (discord) (#1323)
+
+`WebhookURL` global setting for discord is removed and will quit matterbridge.
+New `AutoWebhooks=true` setting, which will automatically use (and create, if they do not exist) webhooks inside specific channels. This only works if the bot has Manage Webhooks permission in bridged channels (global permission or as a channel permission override). Backwards compatibility with channel-specific webhooks. More info [here](https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample#L862). 
+
+## New features
+
+- discord: Create webhooks automatically (#1323)
+- discord: Add threading support with token (discord) (#1342)
+- irc: Join on invite (irc). Fixes #1231 (#1306)
+- irc: Add support for stateless bridging via draft/relaymsg (irc) (#1339)
+- whatsapp: Add support for deleting messages (whatsapp) (#1316)
+- whatsapp: Handle video downloads (whatsapp) (#1316)
+- whatsapp: Handle audio downloads (whatsapp) (#1316)
+
+## Enhancements
+
+- general: Parse fencedcode in ParseMarkdown. Fixes #1127 (#1329)
+- discord: Refactor guild finding code (discord) (#1319)
+- discord: Add a prefix handler for unthreaded messages (discord) (#1346)
+- irc: Add support for irc to irc notice (irc). Fixes #754 (#1305)
+- irc: Make handlers run async (irc) (#1325)
+- matrix: Show mxids in case of clashing usernames (matrix) (#1309)
+- matrix: Implement ratelimiting (matrix). Fixes #1238 (#1326)
+- matrix: Mark messages as read (matrix). Fixes #1317 (#1328)
+- nctalk: Update go-nc-talk (nctalk) (#1333)
+- rocketchat: Update rocketchat vendor (#1327)
+- tengo: Add UserID to RemoteNickFormat and Tengo (#1308)
+- whatsapp: Retry until we have contacts (whatsapp). Fixes #1122 (#1304)
+- whatsapp: Refactor/cleanup code (whatsapp)
+- whatsapp: Refactor handleTextMessage (whatsapp)
+- whatsapp: Refactor image downloads (whatsapp)
+- whatsapp: Rename jfif to jpg (whatsapp). Fixes #1292
+
+## Bugfix
+
+- discord: Reject cross-channel message references (discord) (#1345)
+- mumble: Add nil checks to text message handling (mumble) (#1321)
+
+This release couldn't exist without the following contributors:
+@nightmared, @qaisjp, @jlu5, @wschwab, @gary-kim, @s3lph, @JeremyRand
+
+# v1.20.0
+
+## Breaking
+
+- matrix: Send the display name instead of the user name (matrix) (#1282)  
+  Matrix now sends the displayname if set instead of the username. If you want to keep the username, add  `UseUsername=true` to your matrix config. <https://github.com/42wim/matterbridge/wiki/Settings#useusername-1>
+- discord: Disable webhook editing (discord) (#1296)  
+  Because of issues with ratelimiting of webhook editing, this feature is now disabled. If you have multiple discord channels you bridge, you'll need to add a `webhookURL` to the `[gateway.inout.options]`. See <https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample#L1864-L1870> for an example.
+
+## New features
+
+- general: Allow tengo to drop messages using msgDrop (#1272)
+- general: Update libraries (whatsapp,markdown,mattermost,ssh-chat)
+- irc: Add PingDelay option (irc) (#1269)
+- matrix: Allow message edits on matrix (#1286)
+- xmpp: add NoTLS option to allow plaintext XMPP connections (#1288)
+
+## Enhancements

+[![GoDoc](https://godoc.org/github.com/disintegration/imaging?status.svg)](https://godoc.org/github.com/disintegration/imaging)
+[![Build Status](https://travis-ci.org/disintegration/imaging.svg?branch=master)](https://travis-ci.org/disintegration/imaging)

+
+Package imaging provides basic image processing functions (resize, rotate, crop, brightness/contrast adjustments, etc.).
+
+All the image processing functions provided by the package accept any image type that implements `image.Image` interface
+as an input, and return a new image of `*image.NRGBA` type (32bit RGBA colors, non-premultiplied alpha).
+
+## Installation
+
+    go get -u github.com/disintegration/imaging
+
+## Documentation
+
+http://godoc.org/github.com/disintegration/imaging
+
+## Usage examples
+
+A few usage examples can be found below. See the documentation for the full list of supported functions.
+
+### Image resizing
+
+```go
+// Resize srcImage to size = 128x128px using the Lanczos filter.
+dstImage128 := imaging.Resize(srcImage, 128, 128, imaging.Lanczos)
+
+// Resize srcImage to width = 800px preserving the aspect ratio.
+dstImage800 := imaging.Resize(srcImage, 800, 0, imaging.Lanczos)
+
+// Scale down srcImage to fit the 800x600px bounding box.
+dstImageFit := imaging.Fit(srcImage, 800, 600, imaging.Lanczos)
+
+// Resize and crop the srcImage to fill the 100x100px area.
+dstImageFill := imaging.Fill(srcImage, 100, 100, imaging.Center, imaging.Lanczos)
+```
+
+Imaging supports image resizing using various resampling filters. The most notable ones:
+- `Lanczos` - A high-quality resampling filter for photographic images yielding sharp results.
+- `CatmullRom` - A sharp cubic filter that is faster than Lanczos filter while providing similar results.
+- `MitchellNetravali` - A cubic filter that produces smoother results with less ringing artifacts than CatmullRom.
+- `Linear` - Bilinear resampling filter, produces smooth output. Faster than cubic filters.
+- `Box` - Simple and fast averaging filter appropriate for downscaling. When upscaling it's similar to NearestNeighbor.
+- `NearestNeighbor` - Fastest resampling filter, no antialiasing.
+
+The full list of supported filters:  NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine. Custom filters can be created using ResampleFilter struct.
+
+**Resampling filters comparison**
+
+Original image:

+The same image resized from 600x400px to 150x100px using different resampling filters.
+From faster (lower quality) to slower (higher quality):
+

+
+### Gaussian Blur
+
+```go
+dstImage := imaging.Blur(srcImage, 0.5)
+```
+
+Sigma parameter allows to control the strength of the blurring effect.
+
+Original image                     | Sigma = 0.5                            | Sigma = 1.5

+
+### Sharpening
+
+```go
+dstImage := imaging.Sharpen(srcImage, 0.5)
+```
+
+`Sharpen` uses gaussian function internally. Sigma parameter allows to control the strength of the sharpening effect.
+
+Original image                     | Sigma = 0.5                               | Sigma = 1.5

+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_sharpen_0.5.png) | ![dstImage](testdata/out_sharpen_1.5.png)
+
+### Gamma correction
+
+```go
+dstImage := imaging.AdjustGamma(srcImage, 0.75)
+```
+
+Original image                     | Gamma = 0.75                             | Gamma = 1.25

+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_gamma_0.75.png) | ![dstImage](testdata/out_gamma_1.25.png)
+
+### Contrast adjustment
+
+```go
+dstImage := imaging.AdjustContrast(srcImage, 20)
+```
+
+Original image                     | Contrast = 15                              | Contrast = -15
+-----------------------------------|--------------------------------------------|-------------------------------------------
+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_contrast_p15.png) | ![dstImage](testdata/out_contrast_m15.png)
+
+### Brightness adjustment
+
+```go
+dstImage := imaging.AdjustBrightness(srcImage, 20)
+```
+
+Original image                     | Brightness = 10                              | Brightness = -10

+
+### Saturation adjustment
+
+```go
+dstImage := imaging.AdjustSaturation(srcImage, 20)
+```
+
+Original image                     | Saturation = 30                              | Saturation = -30

+## FAQ
+
+### Incorrect image orientation after processing (e.g. an image appears rotated after resizing)
+
+Most probably, the given image contains the EXIF orientation tag.
+The stadard `image/*` packages do not support loading and saving
+this kind of information. To fix the issue, try opening images with
+the `AutoOrientation` decode option. If this option is set to `true`,
+the image orientation is changed after decoding, according to the
+orientation tag (if present). Here's the example:
+
+```go
+img, err := imaging.Open("test.jpg", imaging.AutoOrientation(true))
+```
+
+### What's the difference between `imaging` and `gift` packages?
+
+[imaging](https://github.com/disintegration/imaging)
+is designed to be a lightweight and simple image manipulation package.
+It provides basic image processing functions and a few helper functions
+such as `Open` and `Save`. It consistently returns *image.NRGBA image 
+type (8 bits per channel, RGBA).
+
+[gift](https://github.com/disintegration/gift)
+supports more advanced image processing, for example, sRGB/Linear color
+space conversions. It also supports different output image types
+(e.g. 16 bits per channel) and provides easy-to-use API for chaining
+multiple processing steps together.
+
+## Example code
+
+```go
+package main
+
+import (
+	"image"
+	"image/color"
+	"log"
+
+	"github.com/disintegration/imaging"
+)
+
+func main() {
+	// Open a test image.
+	src, err := imaging.Open("testdata/flowers.png")
