^C^B isn't allowed through Discord's API, and I'm sure some other stuff
like colors that I don't use. this makes it a server option to replace
them with Markdown, though I think this would only ever be interesting
for BitlBee + Discord
this is necessary for supporting multiple irc servers in one bot config.
this also has the side effect of requiring some code in ircbot and
markov which autocreates channels to also include the server (retrieved
via the connection). this will again help keep channels coherent for
multi-server arrangements
the twitter bot change here is untested but seems like the right idea (I
haven't used the twitter package in forever)
this is the first step in trying to get the bot to support multiple
servers with different channels, countdown triggers, and so on
this also ends up affecting some configuration around:
* dispatch
* markov
* admin privmsg form
