Do not listen to block/entity drop events

It appears several mods inject their own drops on the LOWEST priority,
meaning that we capture the existing drops, and the other mod will clear
the (now empty) drop list and add its own, resulting in dupe bugs.

While I'd argue it's somewhat dubious doing this on the LOWEST priority,
it's not a battle I'm prepared to fight. For now, we just remove the
block/entity drop handlers, and handle all drop logic when entities are
spawned.

Fixes #288
