rockbox/apps/gui/wps_engine, branch master

part two of the grand overall wps/skinning engine cleanup work:

2009-08-03T04:43:34+00:00

* rename wps_engine to skin_engine as that was agreed on
* rename music_screen back to wps
* clean up the skin display/update functions a bit
* make skin_data_load setup the hardcoded default if a skin cant be loaded for whatever reason instead of doing it when it is first displayed

ignore any gui_wps or wps_ or gwps_ nameing in skin_engine/ ... these will be renamed as this work gets finished
