Complete renovation of the external style API:

 - created two QCom interfaces in "styleinterface.h"
 - moved the liquid/theme settings apps into the plugins
 - modified the plugin interface for all three styles
 - extended appearance to fully support the new API (replaces the
   settings apps)

Additional work:
 - made a workaround in appearance for a Qt Bug -- now a QDialog again
   (this should really be fixed in Qt, but Z won't work that way)
