[CDF-287] - As a user, I want to be able to define a chart made up of arbitrary, compatible, plots.

[CDF-301] - CCC - Sunburst color scale no longer inherits color from parent slice.

* Replaced use of legacy cdo.DimensionType#getPlayingPercentVisualRoleDimensionMap() with pvc.Panel#visualRolesOf
* Specifying the new Sunburst "colorMode" option with value "slice", to maintain expected behaviour by the ccc_wrapper.js code.
* Replaced explicit call to valueFormat, to format a percentage, by the new percentage formatting exposed by the DimensionType's format provider.

@pamval please review.
