devel/py-django-tastypie-mongoengine: Fix RUN_DEPENDS

* Assign the port to Django 2.2 (current LTS release) to unbreak the build
  when testing the RUN_DEPENDS.

  This should have already been done in r531187 when I updated and assigned
  www/py-django-tastypie to Django 2.2.

*  Bump PORTREVISION for dependency change.

Use PY_FLAVOR for dependencies.

FLAVOR is the current port's flavor, it should not be used outside of
this scope.

Fixing my previous commit message, which was missing logic:

Instead of using www/py-django111, which is DEPRECATED, use www/py-django111

Use www/py-django111, which is DEPRECATED, use www/py-django111

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

Remove ${PORTSDIR}/ from dependencies, categories d, e, f, and g.

security/py-crits must use django v1.6 and will not work with v1.8
Two dependencies bring in www/py-django so I have created two new slave ports
which
use www/py-django16

* devel/py-django-tastypie-mongoengine allowed you to select django 1.6 or 1.8
in the options It now uses only 1.8
* add slave port devel/py-django16-tastypie-mongoengine which uses django 1.6
* www/py-django-tastypie now sets RUN_DEPENDS only if not already set
* add slave www/py-django16-tastypie which uses django 1.6
