cad/k40-whisperer: Replace reference to PY_PILLOW with its value

Since this port works with Python 3.6 and later, the value of
PY_PILLOW doesn't change. So replace reference to it with its value.

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.

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.

Follow up on graphics/py-pillow6 port removal in r559976

The graphics/py-pillow6 port was removed in r559976 as it was for
Python 2.7 only and no longer referenced in the default cases.
However it was still defined in Mk/Uses/python.mk in PY_PILLOW,
leaving a dangling reference.

Remove it from Mk/Uses/python.mk, leaving only the Python 3
version of that port, graphics/py-pillow, defined and bump the
minimal verion of Python to 3.6 for affected ports.

graphics/py-pillow: Update to 7.0.0

* Repo-Copy the Pillow 6.2.2 release to graphics/py-pillow6 to retain
  backwards compatibility for Python 2 consumers as the Pillow 7.0.0 release
  dropped the support for Python 2.

* Apply conditional statements to use either Pillow 7.x or Pillow 6.x for
  consumers that can be built for Python 2 or newer.

* Exceptions are ports that can be built only for either Python 2 or
  Python 3.  For the first case, consumers are just assigned to the
  repo-copied graphics/py-pillow6.

* Also remove Pillow from BUILD_DEPENDS of math/py-PyWavelets as it is not
  listed in setup.py as a build dependency [1] and relax the version

Changelog:

- http://www.scorchworks.com/K40whisperer/k40whisperer.html

- Do not set PKGNAMEPREFIX to the Python package name prefix. The software
  does not care about the underlying Python version and supporting flavors
  is not worth it in this case.
- Mark the port as working with Python 3.7.
- Set DESKTOP_ENTRIES, USES=shebangfix, and NO_ARCH.
- Put variables in order.
- Change the way files are installed so that it is easier to spot a change
  in pkg-plist in the future.
- Fix Python script indentation issues (mixed up tabs and spaces) in
  post-patch.
- Suggest the user to look in the docs directory instead of the data
  directory for notes about Linux and macOS setups.

GUI control software for the stock K40 laser cutter controller

K40 Whisperer is an alternative to the Laser Draw (LaserDRW) program that
comes with some Chinese laser cutters. It reads SVG and DXF files,
interprets the data and sends commands to the K40 controller to move the
laser head and control the laser accordingly. K40 Whisperer does not
require a USB key (dongle) to function.

Features:
- Reads SVG files and DXF files.
- Splits input design based on color formatting (red, blue).
- In SVG files blue and red paths are interpreted as vectors for vector
  engraving and cutting. Everything else is transferred as a raster image.
