Space Cadet Pinball port

Notes/warnings:

• Game assets are not packaged. Requires game assets from the Windows XP version of the game. (C:\Program Files\Windows NT\Pinball)
• Sound effects are working. Background music however doesn't work yet due to missing MIDI support from the sdl2_mixer package.
• The game needs to be started from the game assets directory, needs the assets directory as the working directory. The game executable is called SpaceCadetPinball.
• Resizing the game window is broken.
