milkytracker: add desktop file
alsa-lib: build without debug by default

now that all alsa issues are (hopefully) fixed, having debug mode
by default doesnt make sense, especially given the bloatedness
of alsa-lib.
bump kernel to 3.10.5
add rc.local with some predefined things to run on boot

this should make it much quicker to get set-up,
it has entries for dhcp, static ip, alsa, and keyboard maps.
