[Pkg-anonymity-tools] Bug#788099: mat missed dependency gir1.2-gtk-3.0

[intrigeri]

Control: tag -1 + pending

Hi,

thanks! I've added a Recommends in the experimental branch of the
Vcs-Git. A Depends would be too strong IMO since mat(1) can be used on
headless machines that have no use for GTK+, and Recommends are
enabled by default, so the vast majority of desktop users will then
have a working GUI as a result.

Cheers,
