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.

INSTALLS_ICONS: retire the macro and rework the related dependencies

While here, make sure gtk-update-icon-cache is only on run dependency
where added as a dependency
Enforce gtk3 to depend on gtk-update-icon-cache (previously it was
inheriting the dependency)

Remove # $FreeBSD$ from Makefiles.

Multiple ports: improve regex compliance

These changes largely fall into just two categories:

1. Need textproc/gsed for GNU extensions
2. Extraneous escapes that can go away

For #1, there's a further subdivision into those that require autoconf magic
and those that can get away with BINARY_ALIAS=sed=${LOCALBASE}/bin/gsed.
-CURRENT will soon gain GNU extensions, but these will take longer to get to
all supported releases; we must switch them to gsed to ensure we're actually
properly building them as intended.

For #2, I've fixed these as I can and we should upstream these fixes.

x11*: Add missing USES={gl,gnome,mate}

Remove libintl.so.9 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

Cleanup plist

Convert a bunch of USE_XZ to USES=tar:xz.
