make colors user adjustable. expose hidden options.

- Systematize colors and make them user adjustable. See documentation for details.
  this requires the \moderncvcolor to be issued BEFORE \moderncvstyle.
- all styles: make the head options 'details' and 'nodetails' available to the user.
(previously they were hidden). Olystyle does not respond too well to nodetails.
