As per meta-androcto's request, I am re-submitting this patch.
I have created an Add-on that will add two camera rigs with UI to the Add > Armature menu
This gives greater control and flexibility than just having a plain camera object.
It is extremely useful for scenes that have a moving camera.

Please let me know if there is anything I need to fix/improve with the code.
