- outsourced some classes cc_item.cpp/h, cc_draw.cpp/h
- added extra methodes for simple use of some basic components extra.cpp/h
- rework clock handling: use timer class, reworked members for
  enable/disable clock with external timer events,
  tryed to fix some display issues related with infoclock and
  time osd clock in moviebrowser, channellist, menuus
- reworked hide/kill handling, removed parameter for hide(), try to use
  cached backgrounds for other constallations, paint cache, image cache (all beta)
- reworked shadow/frame handling, add shadow modes for left/right
  arrangement, TODO: repaint for existant instances required
- reworked color gradient assignment (beta)

and i tryed to restore my historie, but most was lost. Therefore here
the commit is large
