-lets use the old gui_sound.cpp, because we shouldnt force set

Browse Source 
the memory we use for them, not that we get problems
-added debug prints about how much mem left before and after
cleanup
-updated devicehandler, partition handler and usb code to the 
latest usb loader gx one, should give more compatility and
port 1 support (not enabled yet)
