This bug comes with a patch when I've written it. It will show how a plasma5 mix-in could be added.

This plasma5 mix-in is a direct copy of the Gentoo KDE team's effort on getting KDE SC 5 as a whole into the Gentoo tree. I've given them proper credit, and the Gentoo headers have been left in place so it's easy to spot when they need updating.

This mix-in conflicts with the kde mix-in. Plasma 5 can co-exist with KDE, but Funtoo has designed the kde mix-in in a way that cannot allow for Plasma 5 to co-exist.
