Clean up USES

With hat:	portmgr

Deprecate a few zope 2 or 3 components

With hat:	portmgr

Use PY_FLAVOR for dependencies.

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

Switch all pypi.python.org WWWs to a new PyPi home pypi.org where
they now redirect to anyway. All new urls checked to return 200,
I've fixed a couple of them in the process.

Canonicalize PyPi WWWs:
- Switch to https://
- Remove trailing slashes

Approved by:	portmgr blanket

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

www/zope213: update to 2.13.24

Remove ${PORTSDIR}/ from dependencies, categories r, s, t, and u.

- Convert textproc/ to USES=python

With hat:	python@

- do not use easy_install, convert to auto-generated packing list
- move DIST_SUBDIR upper, where appropriate
- add trailing slash to WWW url, where appropriate
- bump PORTREVISION

Tidy up zope/plone ports over the tree. Common changes:
- remove indefinite article from COMMENT
- align USE_PYDISTUTILS value in Makefile
- tab -> space change in pkg-descr:WWW
- update WWW to use https scheme in url to avoid redirect
- add trailing slash to WWW

All changes are non-functional.

Add NO_STAGE all over the place in preparation for the staging support (cat:
textproc)

- Update to 3.7.3

- transfer maintainership for my zope-ports to zope@
- add them to virtual category `zope'

- Add sixth portion of dependencies needed for Plone 4 import.
