AI fixes, borg PDA fix, minor map fixes

Changes:
1) The AI "Show Camera List" button now works.
2) The AI no longer has to use the intercoms to speak on different channels - the regular department codes now work. For instance, to speak in command, use <say ":c Example">. 
3) Borgs can now send PDA messages.
4) Minor map fixes to the NT Representative's/Blueshield's Office.
