Remove the pipe connection and temporarily switch over to using a DummyCamera for testing purposes.
Remove camera status from API / web controls; not currently used, and it can always be added back again at a later date if needed.
Create more random images with DummyCamera (for testing).
Remove unneeded import.
Added a new experimental camera class that does not create a new picamera.Camera instance every time it takes a picture. Should speed up picture taking considerably if it works.
