Theme Switcher

I implemented a theme switcher which will allow the reader to choose which theme they would like to view the site as. This option can be found with the rest of the page navigation options off to either side. It is important to note that not all themes have the same options, as such some themes may have things that others do not, such as the calendar. In any event should I create or get new themes they will automatically appear in the list and you will be able to pick them. As of right now most of the themes have the selection as a list, with the exception of I think one which uses a dropdown selection box. Should I acquire a numerous amount of themes, which is possible, I may opt to go back and make them all dropdown selection boxes to conserve space. Only time will tell. In any case I hope this feature is enjoyed by all, as I enjoyed putting it in.
