Changes to directory structure for website

[Aaron Gyes]

We've moved the website out from the main svn trunk. It's now at
quake3/webspace, instead of quake3/trunk/web, so regular source code
checkouts won't need to get the web stuff along with their code.

If you actually want the website, check it out with:
svn co svn://svn.icculus.org/quake3/webspace ioq3website

If anything we don't know about has been broke, let us know!
