Camera Mapping Overhaul

Camera's will now get their c_tag, network, and direction set at round
start.  When mapping all you have to do now is place a camera on a tile
next to a wall, window or grille.  It will auto rotate on round start to
face the right direction.  Also it will pull the area name for C_tag and
network assignments.

Also have added the Guard Post (unbuilt atm) to Medbay,Research, and Engineering.  These will be used in a future job update.
