This involves a large amount of change in test scene setup code to allow test scenes to share shared modules
SetupScene is now an instance method that requires an instantiation of SceneHelpers, though other SceneHelpers methods are still static
May split these out into separate classes in the future.
Update() now accepts a frames parameter which can control the number of frames updated.
-1 will update until shutdown.
The watchdog updating moves above the maintc recalculation for any required sleep since it should be accounted for within the frame.
I thought that I had implemented this but must have accidentally removed it.
Adds a regression test to detect if this happens again.
Temporarily disables automatic landing of NPC at a target. Will be fixed presently.
