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.

Grab maintainership for this useful little script.

Reset maintainership to ports@ after ~4 months without any response to any
PR.

Thanks for contributing.

Since the acroread7 port is a somewhat important port for our users, I
will hand it over to emulation@ if no _active_ *committer* takes it
before the ports freeze.

While I'm here:
 - fix a little nit in the csound port (I think the intention was to
   create no backup file instead of creating one with a "-e" extension)
 - set ARCH to i386 in the amd64 case for the acroread7 port. This
   is a work-around to be able to install everything when a dependency
   is not already installed (ARCH is read-only in sub-makes, so the
   dependencies can't change it). This should be removed when the
   dependencies are fixed or converted to use bsd.linux-rpm.mk. [1]

Hash with SHA-256.

Use PLIST_FILES.  Be less verbose.  Drop maintainership.

Add size data.

Retire comment file.

Use ${PERL5} instead of hard-coded /usr/bin/perl.

Correct several errors.
