New Exception-System

We decided to implement a new Game-Exception-System using
Bukkit-Listeners which is extremely simple, so even noobs can use it now
:)
Deprecation-Final-Removals

We removed some old deprecated methods and classes, e.g. the TagUtil
which was replaced by MetaUtil or the old APIListener for TagUtil.
ScheduleTask with runXXX()-Methods

The ScheduleTask now uses the runXXX()-methods of the Bukkit-Scheduler,
so you can run async-tasks again!
