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).
