Dank Software Depot 0.9.7

Thanks to @gitblit for the report and the screenshot behind this one.

• The window uses the theme's own background, like the rest of DMS. It
  reacted to theme changes and stayed within the spirit of the palette, but it
  painted a surface of its own choosing, which read as slightly out of place
  next to DMS Settings. It is now built on the same floating window the shell
  uses for its own: the same background tone, the same rounded corners, the
  blur behind it, and the border the shell gives every floating window. It
  also follows the floating-window transparency setting, which it used to be
  deaf to.
