Updated !draw and !forfeit so that it'll do checks even if you voted.

This means that you can still draw or forfeit even if you voted and then someone left (in which case maybe less votes are needed so we have enough votes now).
Updated ban list fast system to prevent crashes on exit nice.
Fixed error with previous commit.
Fixed bug where observers leaving would cause winner to be set.
Might fix crash on some systems relating to MySQL error.
Merge branch 'master' into donate
