Review request for KDevelop.


Repository: kdevplatform


Description
-------

This fixes 2 issues:

*Currently rainbow highlighting only works for the first 10 declarations in Function and Other contexts. All other declarations get highlighted with the default color.
*The current interpolation algorithm is very poor, it can generate only about 10 different colors, all other look alike.
    
So this patch adds ~35 distinguishable colors, which should be more than enough for most cases.
