rockbox/apps/menu.c
Justin Heiner b5025a8c40 USB Related: 
Consolidated some more of the USB code in the WPS.
    Have backlight turn offf when USB Connected.
menu.c:
    LINE_X was set wrong for player.
settings_menu.c / wps-display.c:
    Added 1 Line ID3+. Has progress bar & Kbps.
    Renamed some of the WPS options to be more readable.
wps.c / wps-display.c
    Fixed problem with FF/REW when 'Remaining Time' is on.
    Added %pb to the WPS mix. Player progress bar thingy.
    Thanks to whoever fixed my PLAYER_PROGRESS function :-)
    Changed how volume changes on player (works better now).
    General cleanup of Custom WPS code.
