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/kms-cmake-utils: chase CMake update

This port substitutes the CMake version number into filenames
so its PLIST_SUB needs updating with each CMake update.

One more small cleanup, forgotten yesterday.

Update devel/cmake to latest upstream release, 3.16.2

This new release has support for the latest Boost, Objective-C
and various small improvements. The release notes are at:
	https://cmake.org/cmake/help/v3.16/release/3.16.html

Two ports could not be persuaded to build with this new release
(math/openmesh science/fleur) and are marked BROKEN. Other build
fixes have already been done in-tree.

Thanks antoine@ for the exp-runs (multiple).
Thanks tcberner@ for prep-work (most of the work, actually).

Update devel/cmake to 3.15.2 (latest upstream release)

For FreeBSD, not much interesting has changed. Swift language support
might be useful.

A few ports were fixed as part of this exp-run (libemos not really
related to the CMake update, but in general). Thanks to antoine
for the exp-runs, tcberner for doing most of the prep-work.
