Fix stanza clobbering when replying to errors.

If a stanza handler raised an exception, the exception was processed
and replied by the modified stanza, not a stanza with the original
content.

A copy is now made before handler processing, and if an exception occurs
it is the copy that processes the exception using the original content.

+    The base_plugin class serves as a base for user created plugins
+    that provide support for existing or experimental XEPS.
+
+    Each plugin has a dictionary for configuration options, as well

+
+    The lifecycle of a plugin is:
+        1. The plugin is instantiated during registration.
+        2. Once the XML stream begins processing, the method
+           plugin_init() is called (if the plugin is configured

+        xep          -- The XEP number the plugin implements, if any.
+        description  -- A short description of the plugin, typically

+    XMPP allows for users and agents to find the identities and features
+    supported by other entities in the XMPP network through service discovery,
+    or "disco". In particular, the "disco#info" query type for <iq> stanzas is
+    used to request the list of identities and features offered by a JID.
+
+    An identity is a combination of a category and type, such as the 'client'
+    category with a type of 'pc' to indicate the agent is a human operated
+    client with a GUI, or a category of 'gateway' with a type of 'aim' to
+    identify the agent as a gateway for the legacy AIM protocol. See
+    <http://xmpp.org/registrar/disco-categories.html> for a full list of
+    accepted category and type combinations.
+
+    Features are simply a set of the namespaces that identify the supported
+    features. For example, a client that supports service discovery will
+    include the feature 'http://jabber.org/protocol/disco#info'.
+
+    Since clients and components may operate in several roles at once, identity
+    and feature information may be grouped into "nodes". If one were to write
+    all of the identities and features used by a client, then node names would
+    be like section headings.
+
+    Example disco#info stanzas:
+        <iq type="get">
+          <query xmlns="http://jabber.org/protocol/disco#info" />
+        </iq>
+
+        <iq type="result">
+          <query xmlns="http://jabber.org/protocol/disco#info">
+            <identity category="client" type="bot" name="SleekXMPP Bot" />
+            <feature var="http://jabber.org/protocol/disco#info" />

+    XEP-0050: Ad-Hoc Commands
+
+    XMPP's Adhoc Commands provides a generic workflow mechanism for
+    interacting with applications. The result is similar to menu selections
+    and multi-step dialogs in normal desktop applications. Clients do not
+    need to know in advance what commands are provided by any particular
+    application or agent. While adhoc commands provide similar functionality
+    to Jabber-RPC, adhoc commands are used primarily for human interaction.
+
+    Also see <http://xmpp.org/extensions/xep-0050.html>
+
+    Configuration Values:
+        threaded -- Indicates if command events should be threaded.
+                    Defaults to True.
+
+    Events:
+        command_execute  -- Received a command with action="execute"
+        command_next     -- Received a command with action="next"
+        command_complete -- Received a command with action="complete"

+
+    Attributes:
+        threaded -- Indicates if command events should be threaded.
+                    Defaults to True.
+        commands -- A dictionary mapping JID/node pairs to command
+                    names and handlers.
+        sessions -- A dictionary or equivalent backend mapping
+                    session IDs to dictionaries containing data
+                    relevant to a command's session.
