Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the

Add more PLIST_SUB to Mk/Uses/python.mk

- Add PYTHON_PYOEXTENSION and PYTHON_SUFFIX
- Add PYTHON2 and PYTHON3
- Respect PYTHON_VERSION
- Rename PYOEXTENSION to PYTHON_PYOEXTENSION

This change would help:
- Build databases/postgresql*-plpython with Python 3
  (It has PLIST issue since bsd.python.mk to Uses/python.mk transition)
- Simplify Makefile

The FreeBSD GNOME team proudly presents GNOME 3.18 for FreeBSD.

The offical GNOME 3.18 release notes can be found at
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.

The FreeBSD GNOME team proudly presents GNOME 3.14 and Cinnamon 2.2.
Gnome 3.14.1 and Cinnamon 2.2.16 are supported on FreeBSD 9.3-RELEASE and up.

This commit removes the old GNOME 2 desktop, bindings and some ports that
can't be compiled. A few ports where updated to more recent versions to
allow them to compile with this update.

Apart from updating ports to newer versions

GDM is more integrated with gnome-shell now, and handles several things for
the GNOME desktop such as screen locking. If you want to use GNOME 3 via
startx, you will have to add your own lock screen/screensaver. For example
xscreensaver
can be used for sessions started without GDM.

Shell Extensions can be installed via https://extensions.gnome.org/ , we have
