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.
