Updated The XGL/Compiz HowTo, Created First Theme

The themes for compiz/xgl weren't working because the themes are now made for 'cgwd'. Rather than writing a new howto I just updated the older one.

I was a little tired of all the Vista and OS X lookalike themes and missed one that used to be in the old gcompizthemer called 'calm'. So I tried to make one that resembled the old 'calm' one (which is posted in the howto) but using the new vrunner engine. Try it out and tell me what you think!
