Sender JID can have a `:` inside of it, using `/` as a delimiter now.
Added messageID parser + struct.
messages sent with an attachment do not show replies
But at least common `sendMessage` will make repies from whatsapp to an attachement bridge across.
The new message ID format broke message deleting, so we change the messageID into the real id at the beginning of send.
We really do need the extra info for when we reply to a message though.
