[ANALYZER-2336] - Update rules for applying custom series colors in CCC
* Fixed and cleaned up the code supporting member colors (was broken for quite some time now...).
* Removed the colorFromAnalyzer function, which was needed temporarily to overcome an Analyzer server-side bug in generating color hex strings; that bug has been fixed some time ago.
* Cleaning up the way that the Sunburst's color scale communicates fixed colors to CCC.
* This commit should be accepted at approximately the same time as the corresponding ccc commit, to avoid inconsistent builds.
