v0.4.4

Mostly a bug-fix release - fixed the Surprise Me 1-channel-only playback bug and the mini-player showing stale track durations, plus a bunch of small polish.

New: Windows installer, tabbed Settings, better HVSC global search (title / released / duration / STIL columns), configurable Surprise Me source (HVSC or current playlist), and volume / shuffle keyboard shortcuts.

Thanks to Adam Kazmierski @exploraart for testing + finding the 1-channel bug, and for the trailer.
