https://help.gnome.org/misc/release-notes/3.18/
This update doesn't contain the glib/gtk c++ bindings which will
be done in a another update due to the requirement on c++11 and the
amount of fallout this probably will give.
GDM is still at version 3.16 due to some issues.
Bump mate-themes to use the gtk 3.18 version of the themes.
Thanks to Antoine Brodin for running the exp-runs.
