SweetieChat random cleanup
big mac is a mod.
mods should also be in config.py

close #5 properly this time
inherit from object because reasons
pull SweetieMarkov out of SweetieChat

let's see if we can't make this thing work
helper class for testing markov generation
try fixing message storage
fix up the way SweetieMarkov is called
actually, commands really belong in SweetieChat
inline SweetieRedis

it's actually pretty useless by itself
