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 UNIQUENAME and LATEST_LINK.

UNIQUENAME was never unique, it was only used by USE_LDCONFIG and now,
we won't have conflicts there.

Use PKGBASE instead of LATEST_LINK in PKGLATESTFILE, the *only* consumer
is pkg-devel, and it works just fine without LATEST_LINK as pkg-devel
has the correct PKGNAME anyway.

Now that UNIQUENAME is gone, OPTIONSFILE is too. (it's been called
OPTIONS_FILE now.)

Mostly cosmetic fixes over various Quake2 ports:
- Wrap overly long lines to fit standard terminal width
- When installing pre-generated docs, do not check PORT_OPTIONS:MDOCS
  which is useless in post-stage era
- Simplify MASTER_SITES, optimize away MASTER_SITE_SUBDIR if possible
- Amend COMMENT text and pkg-descr in `quake2-lights' port
- Unbreak installation of Quake2-LNX (icculus.org port)

games/quake2-extras: support stage

Resetting maintainership on ports that have not been staged and without any
pending PR

With hat:	portmgr

Convert g* to USES=zip

Add NO_STAGE all over the place in preparation for the staging support (cat:
games)

Fix a typo made in r317957 during OptionsNG conversion and unbreak the
build; also fix URI of the optional models.zip distfile while here.

Trim Makefile header; convert to OptionsNG (courtesy of jgh@).

This port installs various Quake II extras:

- High quality texture pack (requires support in engine).
- High quality skin pack (requires JPEG and PNG support in engine).
