Pick-ups, Refinement, Ambiance, and Fixes

Hello, again. In the time between the release of the first demo and now, I've been fixing bugs and adding features. I think I've eliminated all of the holes in the geometry that were present in different maps, which is good, though I won't know for sure until someone nudges around somewhere that I haven't thought to try yet.

Soldier Of Windows Demo!

Hey. So, I've finally gotten around to making a demo of the current progress made on Soldier Of. It's pretty crude - there's not that much to see right now, but hopefully if there are any bugs or issues, they can be resolved.
