New package: mypaint-1.1.0_1

MyPaint is a digital painting program, roughly comparable to Krita from the Calligra-Suite, although much more lightweight.
According to the README, python-cairo is needed >=1.4, so maybe I should leave it as a fixed dependency anyway?
I have seen python-gobject2-devel in other templates under hostmakedepends as well. Do I need to move or copy that too?
