v2.10.0

TinyIce 2.10.0

Added: a sandboxed directory browser for the AutoDJ music path, bounded
by a new media_roots config key and confined with the same function the
MPD path arguments use; editable MPD control port and visibility, which
had existed in the config and API with no fields in the form; a shuffle
control; burst_size sent by the mount create form.

Changed: deleting an AutoDJ now asks first, and a stopped instance names
the playlist it would resume and its music directory.

Fixed: the OGG format was offered, stored, displayed and never
implemented — an AutoDJ configured as OGG encoded MP3 and advertised
audio/mpeg. The option is gone, the API rejects anything but mp3 and
opus, and stored values are rewritten on load without changing what any
listener receives.
