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.

*/*: Remove redundant '-[0-9]*' from CONFLICTS_INSTALL

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

  renderer from Monotype and we don't (and can't) build with UFST support.

Clean up print/ghostscript9-agpl-base and print/ghostscript9-agpl-x11 and
update them to version 9.23.  Share CMap data with graphics/poppler-data
and update that to 0.4.9.

Details for print/ghostscript9-agpl-base:
- Update to 9.23.
- Drop external epag device.
- Always use fontconfig to find fonts.
- Use ports openjpeg instead of bundled.
- Use bundled lcms2, because upstream forked it.
- Drop dependency on gsfonts.  Newer versions of the fonts are already
  included.
- Depend on poppler-data for CMap files.  It has the same maps except
  Identity-H, Identity-UTF16-H, and Identity-V.

Make print/ghostscript9-agpl-base the default Ghostscript port.  Upstream
changed the license to the AGPL 3 in version 9.07 so print/ghostscript9-base
is stuck at 9.06 which is almost 4 years old now.

Fix the logic in Uses/ghostscript.mk so "agpl" is treated as a real version
on its own instead of as a variant of other versions.

Fix build error.

- Split ghostscript into X11-independent and -dependent parts:

 * print/ghostscript{7,8,9,9-agpl}-base

   Installs Ghostscript binary, libgs, and related files.
   These ports do not depend on X11 libraries (i.e. x11* devices
   are not available).  USES=ghostscript will set dependency on
   one of them depending on GHOSTSCRIPT_DEFAULT.

   The default device is set to "display" or "bbox".

 * print/ghostscript{7,8,9,9-agpl}-x11

   Installs a shared library which provides X11 support to
   the installed Ghostscript binaries.  x11* devices will be
