[PATCH 1/3] kernel-shark-qt: Improve the KsQuickContextMenu

[Yordan Karadzhov <ykaradzhov@vmware.com>]

In this patch the KsQuickContextMenu gets upgraded according
to the user feedback, received from Steven. First of all a
"Show CPU X only" action is added to the version of the menu
that gets opened from the Table widget. In addition to this
"Apply filter to XX" check-boxes are added in order to control
the visibility of the filtered data.
