Subject: [PATCH] Move setBlock tile->tile transition workaround into TE
removal code and out of setblock
Works around an issue in which running it in setBlock for all block changes could cause sign (and other?) data corruption.
Also tells CB's TE fixer to ignore removals, as it would end up in a state in which it'd set the block, then
call TE removal, which would get the TE to remove, then making CB's fixer run and get confused as to the current state of
the block, but we don't care because that's the whole reason we're removing it.
