Review for the gsoc UI cleanup for the BGE

Review for the gsoc UI cleanup for the BGE.
Surviving commits are:
 - Game Engine UI cleanup: removing Scene/Active Clip
 - Game Engine UI cleanup: Adding missing 'not available' labels in empty panels
The rest was reverted for being subjective and polluting the UI code with an if for every button:
