(Console) Better way to 'restart' instead of using the function 'restart' - call rarch_set_fullscreen instead. 'Restart' function in driver interface can go now (Menu) Menu now gets properly deinited/reinited when - say - rarch_set_fullscreen is toggled or some other state change like this. If init_assets function of menu_ctx_driver is implemented, this should ensure all GL/D3D assets get 'cleaned up' prior to teardown of the video driver, and properly reinited after the video driver is brought up again
