Subject: [PATCH] Enable multiple replies for plugins

This patch adds the ability for plugins to send multiple messages
back in response to a command/message.  The plugin simple needs
to return a list of messages (Strings).  Each string in that list
will result in a separate message being sent back to the originator
of the message.
