Subject: [PATCH] Improve death events
This adds the ability to cancel the death events and to modify the sound
an entity makes when dying. (In cases were no sound should it will be
called with shouldPlaySound set to false allowing unsilencing of silent
entities)
It makes handling of entity deaths a lot nicer as you no longer need
to listen on the damage event and calculate if the entity dies yourself
to cancel the death which has the benefit of also receiving the dropped
items and experience which is otherwise only properly possible by using
internal code.

Subject: [PATCH] Mob Pathfinding API
Adds an API to allow plugins to instruct a Mob to Pathfind to a Location or Entity
This does not do anything to stop other AI rules from changing the location, so
it is still up to the plugin to control that or override after another goal changed
the location.
You can use EntityPathfindEvent to cancel new pathfinds from overriding your current.
