This is a lot but basically adds a method to disable the dropping of experience and drops experience by default. This way things that require XP to be dropped manually (via modification), they can drop XP themselves when needed but without touching anywhere else that may drop xp. It should be noted this causes breakNaturally() to now drop experience.

Setting whether a block break dropped items controlled
|
|
far more than just whether blocks dropped, like stat increases

conversions and beehive releases
