Keen Modding Live - Unifying player page style

I made a couple minor adjustments to Keen Modding Live's web site today:

• The player page now has the same template as all the others. There's still a lot of design that needs to go into that, since it's probably the most important page.
• Level information pages now have an "upload a new version of this level" link that goes to the upload page with the level selected.
