WINGs: Added attribute 'noreturn' to public function 'WMScreenMainLoop'

Browse Source 
As suggested by GCC, this function is a good candidate. There is a little
constraint on how to do it however, as it is part of the public API so we
have to do it in a portable fashion (We can't rely on our "config.h" when
the file will have been installed).
