Much more elegant solution to updating the player's sectnum when passing through 

TROR portals that works with a little help from updatesectorz() (change not visible
from CON code). Relies only on the presence of an extension whose portal isn't
blocked and also plays nicely with corner cases like being shrunk and enabling
the jetpack. This should fix the upward moving platforms in WGR2.
