Improves camera EMP handling. Now uses a var and processing to determine when the EMP should end, preventing inconsistent states when a camera is EMPd multiple times.
Reduces the process and bandwidth need for cameras.
* There is now a common camera repository, responsible for setting up cameras once for every invalidation.
* Camera consoles now only updates when the camera cache is invalidated, not every second.
* The console now only presents one network at a time, and only sends the data necessary to view that network (as opposed to sending the data for all cameras).
Ensures the master area is always used, to avoid issues caused by dynamic lightning which splits areas into sub-areas.
Power alarms now handled centrally.
