v1.15.0

👻 Halloween update: the Halloween theme is animated now, and Clawd has
four spooky skins to dress up in.

• Halloween theme comes alive: fog creeping along the bottom of the widget,
  green will-o'-the-wisps, bats flapping across, a ghost floating by now and
  then and a spider letting itself down from its web in the corner; in the sky
  row a big moon over a graveyard - tombstones, a cross, a dead tree and
  jack-o'-lanterns with a flickering candle inside.
• Four Halloween skins for Clawd: Zombie crab (rotting green, a wound and
  torn rags), Skeleton crab (a skull and ribs), Frankenstein crab (a flat
  top, a scar, neck bolts and a dark jacket) and Dracula crab (red eyes, fangs,
  a widow's peak and a cape with a high collar).
