nbox skin (xbmc wip)

I retrofitted a 7" touch to the factory radio BMW X5. I use openBM daemon monitoring the IBUS on the car to detect radio button events to control XBMC. Also, to maintain original nav system, i have a jammaboard/hdmi switch to swap screens between xbian and on-board-display.

I tried 12.2, but think to fix the dual pointer issues the egalax patch has been removed. I have compiled 12.2 and 13.0 with my modified egalax patch to get my screen working again, no problems, just need to double click. I need to recompile for every new version to maintain my setup.

Hopefully going to use this skin when finished for version 13.0 - http://forum.xbmc.org/showthread.php?tid=159291&page=9

@raspuca - I have only compiled wayland 1.1 with weston desktop -- no software yet early days.
