WSGF Videos Updated to 720p HD YouTube

I've gone through and updated the videos in the Gallery (and re-uploading to YouTube where needed), to take advantage of YouTube's new offerings. The default video format and resolution is now the "High Quality" version displayed at 840x525 (1/4 of 1680x1050). Under each video is a link to view the 720p version in full 1280x720. It's really nice to see the videos in HD; and the Surround videos have a much bigger impact now.
