Subject: [PATCH] Fix FallingBlocks being stuck on fences
Fallingblocks would previously only check if directly beneath them a block exists. They also
hover on top of the 1.5 block tall hitbox of fences during these check. This
resulted in them always thinking they would be on air.
We now first check, if if we are already on the ground.
if not, we check if the falling block is inside of the hitbox of the block at y - 1.
