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 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).
4) Reworks the camera monitor computer. Rather than having the networks set through the circuit board (which, previously, allowed access to hidden networks and requires the user to know the name of the network in the code), the networks can now be set by using an id card on the camera console, or by emagging it. The amount of networks that one can access is determined by the access level of the ID. Also renames the camera circuit board from "Circuit board (security)" to "Circuit board (camera monitor)".
