[WIP] Ultra Gravitron

[darkhog]

OK, I've got permission from Terry to make Super Gravitron-like game (starring Viridian!) .

Features:
* Nauseous, moving black&white background
* Fast-paced action
* Records save file (not in first version)
* Randomly generated enemies

Screenshots:

First tech demo (linux only): http://dl.dropbox.com/u/210143/ultragravitron-techdemo.tar.gz

For now only basic functionality like Title Screen and Viridian's controls (use left/right arrows for that) are done. There are no enemies yet and therefore time counting is disabled as it makes little sense w/out enemies (you can survive indefinitely). Alt+Enter to toggle fullscreen.

Bugs:
- Music in level for some reason don't play correctly. There is nothing I can do, since apparently it is bug in tool I use (Game Develop). This will be probably soon resolved.
- When in level, you can't go back to menu by pressing ESC. This is already resolved in my internal build though.

There will be no Windows build until game will be fully playable (enemies and time counting) though, so don't even ask.
