Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

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.

devel/py-qt5-pyqt: add DBus dependency

This makes DBus explicitly available when installing py-qt5-pyqt,
which is good for desktop use. Previously, building this with
DBus installed **and** pkgconfig and the Python DBus bindings
would trip up in `check-plist`.

Changes:
  - https://riverbankcomputing.com/news/QScintilla_2.13.1_Released

PyQt: Update sip to 6.5.0, reintroduce sip4 and simplify PyQt framework.

SIP:
As mentioned in the update from sip to sip5, this is a transitional version
to remove what is deprecated in sip4.
Sip6 completely removes the deprecated parts.
Unfortunately, some ports — mostly cura things — can not use sip6, so we
reintroduce sip4.

PyQt:
At the same time, we took the opportunity to simplify PyQT and propose only one
package as for devel/pyside2. */py-qt5-* have been merged — excepted chart,
networkauth and webengine — into devel/py-qt5-pyqt.

This allows us to be in adequacy with the packages that the author of these
