New Theme, New Config Editor

I decided to hold off on including the taskbar for the time being, and went back and extended the configuration editor so that it is a little more useful. Also, a lot of code cleanup is being done, so that new stuff can be added easier. The SystemPanel is finished and will be included in the upcoming 0.2.3 release. Also, kuartetdesktop.sourceforge.net is official now, though no site is up yet. One should be coming around the same time as my next release. Documentation is also in the works, but is a hard job since the API is nowhere close to being final.
