AI fixes, borg fixes, map fixes

Changes:
1) Fixed a typo in the Crew Monitoring AI button.
2) The AI is now able to use regular channels using its built-in radio, rather than having to use the intercoms. So if you want to speak in the command channel, simply use :c.
3) Borgs can now send PDA messages.
4) Borgs can now use the camera console.
5) Borgs can now be dragged when their battery is damaged, out of charge or missing.
6) When the AI's wireless system (or transceiver) is disabled, it can no longer interact with doors/talk.
7) Fixes blindfolds
8) Map fixes: Added missing cameras, light switches and air alarms. Fixed up the Blueshield's Office and NT Representative's Office. Added separate areas for the security medbay, security podbay, security secure armoury, security secure hallway, clown's office, mime's office, virology laboratory and escape podbay. These areas were changed/added several months ago with the introduction of new jobs, but they weren't set up properly.
