Add back @dirrm for share/gtk-3.0, which was mistakely removed in
the gtk+ update to 3.8.

The FreeBSD GNOME team presents a Glib and Gtk+ 3 update.

This update updates Glib20 to 2.36 and Gtk+ 3.8

* The gio-fam-backend port that used gamin for the GFileMonitor API is gone.
  It is replaced by a GIO kqueue implementation developed as part of a NetBSD
  GSoC 2011 project by Dimitry Matveev.
* Fix a bug in the glib20 Makefile so it includes -lintl in the glib-2.0
  pkgconfig file [1]. This broke static linking and newer binutils.
* Add introspection USE_GNOME component which sets GI_SCANNER_DISABLE_CACHE to
  prevent creation of /  root/.cache dir. Defaults to build & run depend,
  but :build and :run switches available.
* New x11-toolkits/pangox-compat port and companion USE_GNOME component for
  pangox support which was removed from the pango port. Add it to ports still
  using pangox API.

- Convert USE_GETTEXT to USES (part 3)

Approved by:	portmgr (bapt)

* Update the glib to 2.34.3 and gtk20 to 2.24.17 and gtk30 to 3.6.4 which
  are the latest stable releases.
* Update vala to the newest stable release 0.18.1, also update a few ports
  in the gtk/gnome stack.
* The c++ bindings ports for glib, atk, gconf, etc, have now USE_GNOME toggles.
* Remove pkg-config run depends from glib20 and freetype2. This doesn't
  eliminate pkg-config run dependency completely, a second phase is needed
  and is planned.
* Support for .:run. and .:build. for USE_GNOME components was added.
  Currently only libxml2 and libxslt support this mechanism.
* Updates of the telepathy stack and empathy.
* Trim makefile headers, convert ports to new options, trim off library
  versions for some ports.
* Fix other ports so they build with the new glib version.
