all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Remove some more expired ports:

devel/py-backports.functools_lru_cache
devel/py-backports_abc
devel/py-futures
devel/py-singledispatch
devel/py-typing
graphics/py-pillow6

Adjust dependent ports.

soupsieve 2.0.1 is only compatible with python 3.6+

- Update to 2.0.1

- Revert the previous commit because the new version can not build with python2

- Update to 2.0

www/py-soupsieve: Add missing dependency

soupsieve depends on backports.functools_lru_cache [1] on Python versions <
3, add the dependency accordingly.

While I'm here:

 - Add TEST_DEPENDS and test target to improve future QA

Note: soupsieve 'requires' [2] beautifulsoup4, but beautifulsoup4 depends
      on soupsieve via install_requires, causing a technical circular
      dependency, which is why soupsieve doesn't seem to explicitly
      install_requires on it ... anymore [3]. This seems bizzare.

SoupSieve is a CSS selector library designed to be used with
BeautifulSoup4. It aims to provide selecting, matching, and
filtering using modern CSS selectors. SoupSieve currently
provides selectors from the CSS level 1 specifications up
through the latest CSS level 4 drafts (though some are not yet
implemented).
