Run Rockbox as a service, which allows for music decoding&playback in the background,

the activity only attaches to the framebuffer for displaying it. An icon
in the notification area is displayed (it could be prettier I guess).

Note: Some HTC phones won't, includng mine, get enough CPU time to do background decoding
fluently, see: http://code.google.com/p/android/issues/detail?id=9663
