Mk/Uses/magick.mk: Bump all consumers

Bump all consumers of ImageMagick ports after flavorizing them.

Approved by:	tcberner (mentor, implicit)

audio/opus: bump consumers after update to 1.4

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.

graphics/kxstitch: pet stage-qa

framework: Add new USES 'magick' for graphics/ImageMagick*

A new USES has been added to depend on ImageMagick.

	USES=magick

adds a LIB_DEPENDS on graphics/ImageMagick${IMAGEMAGICK_DEFAULT}.

If a specific version is required, use for example

	USES=magick:6        resp.     USES=magick:7

If only a build, run or test is required, use for example

	USES=magick:build    resp.     USES=magick:6,build,test

KDE not-Applications: chase doctools

These ports use KDE Frameworks and require kdoctools to build. Since
that is no longer an implicit build & run dependency, (re)introduce it
explicitly as a build-time dependency.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories g

Add USES=xorg and USES=gl to ports in categories starting with 'g'.
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

graphics/kxstitch: fix build

Add USES=compiler:c++11-lang to fix build.

Approved by:	mentors (implicite approval)

Update graphics/kxstitch to latest upstream release.

 - patch from git no longer needed
 - This release adds a cropping tool to the image importing function.
   There are several bug fixes with image importing relating to the
   various ImageMagick library versions, and some compilation fixes
   for later KDE/Qt versions.  This release also fixes the file opening
   bug found with later versions of KDE/Qt.
