vinyasa v0.1.0

The first release: Vayu's settings app, starting with how it looks.

• Theme: a card per theme with a tiny desktop drawn in its colours; the
  accent colour; the dark/light twin; terminal transparency; GTK apps on or off.
• Theme editor: start from any theme, change its 26 colours and its
  accents with a live preview, save it as your own, delete it.
• Fonts, Wallpaper (pick one, daily wallpaper on/off, fetch today's)
  and Windows & gaps (gaps, border width, corner radius).
• Tools: give any tool its own theme or switch it off; tools whose
  config doesn't include varna are marked.
• About: versions, re-apply everywhere, every tool's status.
• Every change applies at once through varna, in the background, and the
  window restyles itself to match. A search box finds any setting (theme and
  tool names too); vim keys (j/k, h/l, gg/G, /, ?, q).

Install: kosha install vinyasa (installs varna too).
