More Spit and Polish

The project demo is in just a few days now. So I'm going crazy with minor bug fixes and polishing to ensure the demo goes well. For example:

• The game join menu doesn't crash when no games are available


• The game join menu will poll for new games if none are available


• Beam weapons now do damage when swept through other ships


• All incomplete scenarios are have been disabled


• Fighters have photo****ed textures instead of default test patterns


• Minor damge model bugs fixed


• Thrusters flicker slowly enough to be noticable


• Sound effects fade correctly

Regarding the photo****: One thing I really wanted to do in this game was give the fighters a nice metallic look. Metal is shiny! But, if I add shininess to the game it gets choppy. Ugh. But I might have a solution. Rust! Patina! etc.

I want to avoid making the game a rusty-brown shitefest so I'm hoping to go for more of a tarnished silver/brass/bronze/copper look. If, later, I manage to get some decent shininess at decent speed I'll bring back the metal look I wanted originally.
