Post-blindness display

[Grey]

After being blinded all actors are invisible until they move, including the player. Hovering a mouse cursor over will give a tooltip to reveal the location and details, but the tile and the targeting square are not shown until there is movement. Essentially there need to be more screen updates.

This is also an issue when a rogue comes out of stealth or invisibility ends, so these should be addressed as well.
