FerrumPlay 0.9.4

• The interface comes in three appearances, chosen in the settings the same way FerrumPix offers
  them: dark, gray dark and gray light. The colours are not four stylesheets but one set of keys
  that is rewritten at runtime, so a change takes effect at once, without a restart. A genuinely
  light appearance - dark text on a white ground - was built alongside them and dropped again: it
  looked wrong in this player.
• The player is part of the appearance now. The footer deck, its edge and the seek track, the veil
  over the playlist and over the converter, tag and Lyrion areas, and the scrim over the blurred
  cover used to stand as fixed dark values inside the views; they come from the chosen appearance
  instead, so the two gray ones are not a dark player with a gray window around it.
• Drop-down lists, menus and list rows follow a change of appearance. They read the keys of the
  Fluent theme and not ours, and those are now mirrored after every change - otherwise they stayed
  in the colours of the previous appearance.
