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.

A too sharp axe causes unpredictable damages

Cleanup plist

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it.  Bump PORTREVISION on their dependent
ports except the ones that depend on these:

audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt

In these cases the same trick as in the recent gettext update is used.

- Release ports maintained by games@

games@ team is quite small and inactive, so ports currently assigned
to it cannot be assumed as properly maintained. To not cause confusion
by making it look otherwise, and also to allow and promote adoption
by individual maintainers, release these ports back to the pool. Note
that this does not change the fact that games@ team still takes care
of these ports to excent of its capabilities.
