Andrew's explanation of the head-height wall block quirk, and added two new
assembly options to make the quirk the same in both directions: ignore wall

Incidently, somebody mentioned somewhere that the code at &8A0B is a
remanant from Manic Miner. It cycles all the PAPER on screen whenever &85DC
is nonzero. &85DC is never set to nonzero by the game engine anywhere. I've
searched the message archives and can't find who mentioned it. I'd like to
ensure I credit the correct person for the explanation ;)
