patch 21737 by Elia Sarti (vekoon)

Browse Source 
Currently for ColorBands, when pressing the Add button, new elements are
set with a medium gray in a medium position which often is not desired
behaviour.
 
This patch when possible sets new elements as averaged values between
the current element and its preceding neighbour
