Can be either time-based or points-based. Also, made fwarn a bit smarter
at guessing what the user actually wanted to do based on the parameters
given to it. Warnings now always require acknowledgement, because that
paves the way for a future commit only beginning stasis once a warning
is acknowledged.
Warnings also split off into their own file to declutter wolfgame.py a
bit (now only 9k lines, wooooo! >_>)
Does not play nice with eir, that functionality isn't going to be in the
bot itself but rather some custom code in lykos (hooking into privmsg).
