Camera Fix

- Cameras work properly even without power now.
- Reason for this is that:
1. Cameras were sometimes on space tiles, which had no power. Hacky fix (placing areas on space tiles) had to be used. However constructed cameras won't work.
2. Simply turning off APC power cuts AI's sight of that room. Harpy presumed this is always due to cell being drained (which would make the AI useless) but someone can also turn it off manually
3. If larger power failure (powersink?) occurs, AI is effectively blind. This technically kicks it from the round, as only thing it can do is stare on dark screen unless power is restored. Combined with problems caused by unstable power generation and excessive power usage which are currently on master, this is large issue.
- Technically just reverts @mwerezak's changes to cameras. He probably presumed this is a bug, however for AI players this just ruins gameplay horribly.
