#107 Option for different Screen Backgrounds

[Olivier Leroux]

I'd like an option to include different Screen Backgrounds for the Viewport screen and the character sheet. Changing the Screen Background on other occasions, e.g. depending on the dungeon level, progress within the story etc. would be very nice, too, but not top priority. But if you create a Screen Background especially with the Viewport screen in mind, it won't always look good on the character sheet screen.
