Introduce new extensible virtual categories for KDE

A lot of KDE Ports share MASTERSITES, LICENSE and so one, as they are
released as a bundle upstream, however, there was not really a clean
way to share this information.

Using these new categories, we can simplify the Makefiles for the diverse
KDE ports.
At the moment we support the virtual category
	* kde-kde4
In the future, this will be extended to
	* kde-frameworks
	* kde-plasma
	* kde-applications
