sleep/fatigue bug

APOS has a sleep/fatigue bug on Uranium (perhaps other servers too), where you'll go to sleep but then while sleeping the fatigue number never drops. I've tried poking around a bit. It looks like onSleepFatigueUpdate is not being called when the bug happens (found within SleepListener.java). I haven't checked upstream to see why onSleepFatigueUpdate isn't being called yet.
