Camera consistency fixes round two

Changes:
1) Second part of my major camera naming overhaul for the sake of consistency. No camera has been left untouched, and they should all be named and grouped consistently now. No cameras were added or removed.
2) Updates the restricted cameras update list to reflect the naming changes, and adds the "Xeno" grouping so the AI can no longer see on board of the Xeno shuttle to check the gamemode.
3) Adds a light to Acute 1 (per http://nanotrasen.se/phpBB3/viewtopic.php?f=12&t=2489).

I'm currently also working to overhauling the camera monitor so it's more consistent with other consoles and allows easier network switching. Just to avoid any future merge conflicts I'm including my mapping changes on this one.
