Groovy Palette & Frames 0.2.0

• A live palette browser on the START menu. START → PALETTE scrolls
  the whole list with the game still on screen behind it: the screen
  declares isOpaque = false, and colorisation runs at composite time on
  the finished frame, so moving the cursor recolours the actual game
  rather than a swatch. A keeps what you are looking at, B puts back
  the palette you came in with.

  Thirty extra rungs on an options row you cycle one press at a time is a
  bad way to choose a colour, and choosing it from a menu that is covering
  the game is choosing it blind. This is the answer to both.

• START MENU (on) turns it off again: no menu row, no screen, and the
  palettes exactly as in 0.1.0. The switch is the browser, not the mod.
