Move onground/onroof/animateentities logic to start of gamelogic()

For some reason, it was put near the start of gamerender(), even though
since it handles edge-flipping it seems like it should be in the logic
function already.

This makes sure entity animations don't animate as fast as possible, and
also fixes edge-flipping on normal surfaces.
