Broken again

Split project into three python files
Added UI.Key_Handler
Added Bridge_Mode
Added Car_Status
Added random Entity names
Added Entity.create_timestamp()
Removed Entity.handle_cs()
Wrote Entity.check_for_bridge()
Changed Entity.start() to Entity.main_thread()
Added Entity.start()
Re-added call to EntityManager.set_layer_object()
Wrote EntityManager.start()
Still broken, but less so

Added threading.Thread to Entity()
Messed with how threads are instantiated in EntityManager()
Hand-merged code

Merged a bunch of stuff from master.
Still trying to get it working

Removed threading.Thread from Vehicle.py
Renamed VehicleManager.start() to VehicleManager.start_threaded()
Added VehicleManager.start_round_robin()
Got it working

Removed call to EntityManager.start_round_robin()
Added vehicle movement to Enter for testing purposes since the loop
stuff is weird and broken for now
Merge remote-tracking branch 'origin/maddie-breaks-stuff'

Conflicts:
	.idea/workspace.xml
	UI.py

Merging maddie-breaks-stuff into master, because my version works on some level again
