archivers/gcab: update to 1.6

Changelog:
 New Features:
  - Allow specifying the allowed compression formats at runtime (!15)
    This would allow us, for example, to disable the slightly scary LZX
    compression format when parsing unknown files.
 Bugfixes:
  - Do not require git when building from a tarball

archivers/gcab: update to 1.5

New Features:
 - New gcab_file_set_bytes() API (!8)
 - meson: Register the gcab executable with meson (!10)

Bugfixes:
 - Fixed MSZIP compression when deflate algorithm would expand (#16)

   Previous versions of gcab can produce "incorrect" archives (when a
   compressed block is larger than its input). They are however
   supported by gcab itself, and we will keep support for it for the
   foreseeble future.

 - Fix coverity warnings (!9)

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.
