toolbars from krita. Fix a couple of sig/slot bugs. Reinstate
drag & drop support.

Note: Cyrille should really port the GRAY colorspace so masks work
again and Bart should consider using the ALPHA colorspace instead
of GRAYA for masks.

Still no layers in the layerbox, no idea what's going on. And the
layout of the statusbar is seriously messed up. Plus, sundry lacunae,
bugs and so on. But KisView2 is still a very small class :-)
