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 # $FreeBSD$ from Makefiles.

Let USES=localbase add -L${LOCALBASE}/lib to LIBS instead of LDFLAGS.
USES=localbase:ldflags can be used to set LDFLAGS.  Normally LDFLAGS
appears too early on the command line causing some ports to link with
their own libraries in LOCALBASE (if installed) instead of WRKSRC.

Also make use of _USES_POST so -L${LOCALBASE}/lib is added as late as
possible after anything a port Makefile might set.  Use _USES_POST
instead of .include in libedit.mk and libarchive.mk so things like
'USES=libedit localbase:ldflags' work correctly.

Fix some issues with LIBS in some ports.

Switch ports that don't support LIBS to localbase:ldflags.
