fix broken re-painting of nodes using the split palettes

(broken in multiple places....oy.)

also, fix wrong light green shade in colorwallmounted palette

also, fixed many wrong/missing aliases and translations between old and current colors
(i.e. aqua<->spring, skyblue<->azure, redviolet<->rose)
