(ANALYZER-1699) Stack overflow error when too many charting points have been selected
* Removed analyzer.CCCVizHelper#configProperty method
* Now reading the analyzer.property "filter.selection.max.count" directly from the visualization options.

(ANALYZER-1716) Setting chart series color in Analyzer doesn't work in Pentaho 4.8GA
* Fixed palette determination code crashing in CGG. Now always using the default Analyzer palette, until the way that series colors will be supplied by the VizController is worked out.
