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.

devel/py-ipykernel5: Remove in favor of devel/py-ipykernel

Ports were switched to devel/py-ipykernel5 on 2020-05-07
because devel/py-ipykernel has expired at the time.

Currently main consumers of devel/py-ipykernel - Jupyter and
Spyder - work fine with devel/py-ipykernel.

There is no reason to use an outdated devel/py-ipykernel5 everywhere.

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.

math/py-matplotlib: chase minimum Python version in dependent ports

Since the previous update changed USES=python from 3.6+ to 3.7+, all
dependent ports must have USES=python:3.7+ as well, otherwise it breaks
the @py36 flavor.
