okay, it's time. we got around for a while with all sorts of silly
config options and exceptions and common strings triggering bot
commands. but now it's time to man up and expect modules to be
more strict and less loosey-goosey.
convert the popular modules (i.e. the ones that still work) to
trigger on !pi rather than pi, etc. usually, this is achieved via
regex searches, although there are some weird bugs (ones i'm hoping
are caused by other recursion/alias bugs and not this commit).
more code around this will be gutted soon, but this, at least,
means you can't say 'tweet that shit, yo' and accidentally trigger
the bot.
