devel/py-python-dateutil: Move devel/py-dateutil to devel/py-python-dateutil

- Convert to USE_PYTHON=pep517
- Bump PORTREVISION of dependent ports for dependency change
- While I'm here, update audio/py-pyradio to use PYTHON_PKGNAMEPREFIX instead of
PKGNAMEPREFIX for *_DEPENDS

astro/py-spacetrack: Remove PY_SETUPTOOLS

py-setuptools should be used rather than PY_SETUPTOOLS

devel/py-setuptools: convert individual consumers to ${PY_SETUPTOOLS}

Currently a no-op, but in the future outputs the correct setuptools
port depending on whether USES_PYTHON=distutils is specified.

With hat: python
PR: 270510, 270358

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.

astro/py-spacetrack: Fix RUN_DEPENDS

- Convert to USE_PYTHON=pytest
- Bump PORTREVISION for dependency change

astro/py-spacetrack: Revert 1c0c6b6600785014044919dad0f4b43965ac1385

This change is incorrect.
- py-rush is a runtime dependency.
- USE_PYTHON=pytest should be used, not USES=pytest.

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.

astro: remove 'Created by' lines
