Add multi-project irc support to the bot

This commit adds support for multi-project/channel irc support to the bot.
To do this you list multiple channels in the bot yaml and specify which
projects get reported to that file. When a bug is encountered that targets
the listed project the message will be reported. If 'all' is specified as
a field under projects for a channel then all projects will be reported on
that channel.
