Allow us to take screenshots in menus

[Beed28]

Pretty much what the title says. I have a problem with GZDoom's menu in fullscreen mode, particularly after changing the resolution, but I can't show anybody because, simply put, it's flat out impossible to take a screenshot while the menu's open. PrintScreen doesn't work either because it seems to only capture the initialisation window from when you start up ZDoom.

If I were able to take a screenshot while a menu was open, I would be able to show everybody the problem I have.

Can't be done. Menu inputs eats the screenshot key, and all other keys.
