Track selection enhancement

[thelusiv]

I thought of an easy way to do this. Right now each track has one "track shot" image that gets put into the track selection widget for starting a game. I could set up support for multiple track shots...if anyone is familiar with selecting maps on UT2004, there it fades between different previews after a second or two interval. Thus we could have in the textures directory a subdir called trackshots. One could be the shot we have now. Another could be an overhead map. We could add more preview shots of the track, as well.

Adding track info is another thing I'd like to add, but would be a little trickier. Not at all impossible though. It would just take a little more coding.
