NICE TO HAVES:

- random mods for mods that are not played in game (e.g. for xlogical intro
  mod, instead of having the same mod always play on startup, have the
  property store a ':' separated list of mods that could be used for the
  intro... then on startup, xlogical would pick one of the mods to play
  consistently for that session)
- startup screen could use some funky animations (doesn't really need it but
  if we have some extra time, it might be neat)
- load levels menu item?
- it'd be nice if the high score table kept track of what level the player made
  it to as well as their score (issue is how much screen space do we have?)
- different background tiles (not necessarily hundreds like we had before...
  but a small subset of background tiles would be nice - maybe user selectable
  background tile themes? Logical had 4 different background tiles that the
  user could pick from...)
- real time VU meters in game
