Log Message: 
24-bit color cube collision avoidance (patch by Fengguang Wu)

When the color cube slot is found to be already occupied by a similar
24-bit color, search through the -1, 0, +1 R/G/B indices trying to find
an empty slot, or the oldest used one (which hopefully is no longer in
active use).

This effectively reduces random collisions, hence make it pretty hard to
hit a vim GUI color scheme that cannot be correctly showed in urxvt.
