Tweak AI Camera View to be Observer

[SARazage]

The problem here is that a blacked or static view would show right away where traitor hiding spots are. Currently it's not immediately obvious which cameras are cut. I'm not sure what a good solution to this would be though as I do like the idea overall. Maybe combine it with the ctrl-click movement so you can get to places quickly.

Any AI worth is salt, though, is going to be familiar with what cameras are and are not cut based purely upon "well, can't view that area", not to mention the camera list.

Except that this change would be a very big callout by having a big black or static piece on the map. It pretty much makes cutting cameras pointless then. Right now it would take some time for the AI to figure it out.
