New piece for managing recorded audio samples. Records from notepat are saved as timestamped .raw files to /mnt/samples/ on the boot media. Browse, preview (space), load (enter), and delete (x) saved samples. Adds sound.sample.saveTo() and sound.sample.loadFrom() C bindings for saving/loading sample data to arbitrary paths.
