• = Remove accidentally left-in debugging message from when going on duty.

From 1.1.0:

• + Mobs now won't attack players who are on duty. Previously, when trying to punch pigmen for instance, they would start behaving like usual and start targeting the player.
• + On-duty players cannot put out fires, unless the material 'FIRE' is in the list of blocks that it is allowed to break, or the player has block breaking permission.
• = Restore food level when going off duty. Previously, it was stored when going on duty, but not restored when going off duty.
• ! Save and restore more player variables when going on and off duty: exhaustion, saturation, fall distance, fire ticks, remaining air, velocity.

Also, this version is targeting Java 6 instead of Java 7.
