Subject: add API option for "colorwallmounted" paramtype2

(pass "wallmounted" to the "is_color_fdir" field where needed)

Comes with an abridged, 32-color version of the master palette,
containing Red, Orange, Yellow, Green, Cyan, Blue, Violet, and Magenta,
in three shades each, plus the usual black/three greys/white, plus pink
and brown in two of the extrs spaces.
