gst-debug-viewer for gtk3 / gir

[Stefan Sauer]

hi,

I pushed my porting effort of the gst-debug-viewer. gtk-debug-viewer was
still gtk+2 based and if we'd like to add more features (e.g. GstTracer
graphs), porting sounded like a good idea. While the port kind-of works
it is unfortunately starting up real slow. This might be gtk+3 related
(the treeview model) or gobject introspection (its written in python) -
or both. If anyone can help to profile this, I am running out of ideas.
