[oe] meta-qt5 available

[Martin Ertsås]

Hi.

I have just made a new layer, for qt5 recipes. This contains work in
progress recipes, but should be working. In the (not so) long run, qt5
recipes will hopefully be added to oe-core, but in the meantime these
are available.

The recipes are based on the qt4 recipes in oe-core from 4-5 months ago,
and some of them might be a bit messy. If anyone feels the urge to help
out with this layer, and make these recipes as good as humanly possible,
feel free to do so.

The project is located at git://github.com/martiert/meta-qt5.git

Best Regards
