Select Color: bottom-aligned field, list view, name sorting, book names

- True Color opens in RGB; the gradient field, hex and nearest index sit
  at the bottom so CMYK's fourth slider doesn't move them; slider rows
  closer together.
- Document tab: grid or list view (list drawn like the colour-book bars),
  and Name A–Z / Z–A sorting (translated in all locales). Swatches of
  colour-book colours show the colour's name.
- A colour-book colour picked as the current colour (nothing selected)
  keeps its BOOK$NAME on the objects drawn with it.
