Multiple screen resolutions

[FolkertVanVerseveld]

The original game provides multiple screen resolutions in game and in all menu's for 640x480, 800x600 and 1024x768. Besides supporting these resolutions, it should also provide windowed and fullscreen support and eventually even larger resolutions like 1920x1080, but the latter is probably for a separate issue.

• [X] reshape/update any UI components when the resolution has been changed
• [X] support 640x480
• [X] support 800x600
• [X] support 1024x768
• [x] support fullscreen/windowed mode
  • [x] change window state (display boundaries get fucked up...)
  • [X] toggle with F4/F11
• [X] support even larger resolutions
• [X] change resolution while running the game (e.g. go from 800x600 to 1024x768)

Apparantly, the fucked up window state has to do with my laptop from hell, because it works perfectly fine in the windows build... so ignoring that issue for now...
