this is a big change. DrBotIrc is now in charge of module loading
and unloading, aliases, and recursion. the Alias module is no more,
and a bunch of functionality was moved out of IrcAdmin, including
also config file saving, the sigint handler, and quitting the bot.
additionally, a lot of stuff got caught in the wake. dr.botzo.py
is simpler now, and lets DrBotIRC do the dynamic loading stuff.
Module.__init__ changed, modules no longer get modlist and instead
get a reference to the DrBotIRC object. IrcAdmin still has the same
exposed methods, but now calls out to DrBotIRC to achieve some of
them.
naturally, a recursion/alias rewrite was included with this change.
it is clearer now (i think), but probably brittle somewhere.
additionally, currently any module that has registered a pubmsg
handler can potentially fire more than once on one input (without
recursion). this may be the next thing to fix. do() may need to
be split, or maybe it's time to stop having modules deal with
pubmsg/privmsg entirely. need to decide.
WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
note that nothing megahal is shipped with the bot now, including
train files. this bot will expect a ./megahal.trn, and will write
to ./megahal.brn (in addition to a slew of other ./megahal.*
files).
implementation is from http://megahal.alioth.debian.org/
obviously, we need to call Module.__init__ as well, and as a nice
side effect, doing all of this lets us not need to do the on_connect
nonsense, which was the wrong thing to do anyway
