[Feature Request] Link "camera freezing" to the rest of the camera options in camera.txt so we can assign a keybind to it.

Think something in the line of this:
In this case loading camera2 would freeze the camera. Loading camera 1 will unfreeze the camera.
 
camera_freeze_rotation0=false
camera_freeze_rotation1=true
camera_freeze_rotation2=false

camera_freeze_position0=false
camera_freeze_position1=true
camera_freeze_position2=false

Another additional feature to this, would be a "Refreeze" option.
camera_refreeze1=true

If you load camera one again and freeze is set to true, it will update the camera to the latest position, before freezing it again. Kind of like a toggle, this would be useful in fighting games and games like tony hawk. You could set the world scale to a high value and then just press a button to recentre the game camera.
