Bump version to 0.11 prior to next release.
Fix "AddKey"/"Set" bugs which would sometimes use the wrong camera.

Turns out that the "main" camera changes a lot. Instead use the same
references that the CameraController is using.

This also cleans up the logic around camera acquisition etc.
Remove unused debug logging methods.
Misc project file changes.
Stop CameraControl from being destroyed on scene change.
