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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Bump the Capstone library version to 4

This port is dependant on both the Capstone library and the Python
bindings for Capstone. The version of the library has to be bumped to 4 as
the bindings version has to be kept in sync with the library version in
order to avoid build problems.

devel/plasma: Update to latest snapshot and undeprecate

Upstream has no yet adapted the code to use PyQt5 instead PyQt4. Thus the
option MEMMAP that requires Qt4 has been completely removed to make the
removal of Qt4 in the ports tree somewhat easier.

While I'm here:
* Fix license
* Simply GitHub usage by removing GH_PROJECT
* Add a patch to fix an issue with fake headers (not merged into upstream's
  repository, yet)

Mark QT4 ports/functionality for removal on 2019-03-15

While here, chase some KDE4 ports and functionality, these are scheduled for
removal on 2018-12-31. Change the default option/flavor to QT5 where applicable
or use alternative toolkits like GTK.

pyqt: Change install directories for Python flavor support

* PyQt could not be installed for multiple Python versions at
  the same time, as there were conflicting files.

  This patch creates Python-version versioned directories for
  all these, and further installs binaries with a version number.

* Note, there might be some hickups for software that depends on
  on of the .so's provided by PyQt5, which might not be found
  anymore autmotically, and maybe need some LD-flaggery.

* Update PyQt5 to 5.10.1

* Mark www/py-qt5-webengine broken. It is unforuntately no longer
  compatible with the old qt5-webengine-5.9.4 we ship.

Use PY_FLAVOR for dependencies.

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