Bringing back "Auto Start" option in the Game Menu.

It's (still) not working since the pool in the operator will not allow this operator to run without context.
For the window/area/screen has to be created somewhere (maybe in WM_init_game ).

I have no idea on what should be done to initialize it here, so if anyone knows how to proceed, please help here.
* side note: should we also have it as a command line option?
