The name’s the deal – this changes your wallpaper for the XMB, no more, no less.

Changes:

Added capability of changing/randomizing the background *BEHIND* the XMB wave lines
(WITHOUT touching the flash0:! So, perfectly save )
Read the notes about this in the readme when having trouble with it!
Wallpapers are now finally copied BEFORE the XMB loads, so you see the change imediately, not at the next reboot
Major internal changes (making the plugin pure kernel mode and dealing with the consequences), the usual bug hunting and some cleaning up of the code.
