Merging of my tree.
This contains: * a few capplets were redone UI wise: ui-properties keyboard background-properties * splitting of libcapplet out of this modules (into libcapplet) * new html-based view in the control-center * initial import of functional root-manager This stuff isn't all done yet, but I wanted to get it in. TODO files will hopefully follow.
