[PATCH 8/8] kernel-shark-qt: Remove duplicate code in KsWidgetsLib.cpp

[Yordan Karadzhov <ykaradzhov@vmware.com>]

Currently the "Task" and "CPU" checkbox widgets have their own
implementation of the code that generates the Rainbow color palettes
of the CPUs and Tasks. This patch make the two widgets to use the same
hash tables of colors used when plotting the graphs.
