GM Vision and roofs

With GM Vision active, Overhead tiles that use vision based occlusion don't fade when a token is selected and the GM has to hover over the tile to see the tokens in a room.

I hope that a Core Foundry change will fix this incidentally, but it's best to raise it here too in case we can get an earlier fix for the whole behavior or if GM Vision needs special handling even after core vision gets changed.
