request pending on GitHub).
Making ocropus-hocr run (matplotlib + gdk backend)

I added the gtk backend to matplotlib; if these added dependencies are
too much, we can make this optional.

Now "./run-tests" passes. But it can't be run without DISPLAY, so
I don't run it in the builder.
almir: add psycopg2 dependency
nautilus-sendto: add to gnome 3.10
usermount: New Package.

A simple tool to automatically mount removable drives using UDisks2 and
D-Bus.
