BlockPhysicsEvent no longer necessary

We don't need to wait for detachable blocks to fall after the base block
is broken, because they *will*. Immediately log the associated break
and skip the whole plannedFall/physics system.

BlockPhysics is a very spammy event and getting rid of a listener for it is
a huge plus.
Merging removal of blockphysics. The event is used for cauldron, no vanilla prism
