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.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Remove # $FreeBSD$ from Makefiles.

New port: security/asignify

Asignify tool is heavily inspired by signify used in OpenBSD. However, the main
goal of this project is to define high level API for signing files, validating
signatures and encrypting using public keys cryptography. Asignify is designed
to be portable and self-contained with zero external dependencies. It uses
blake2b as the hash function and ed25519 implementation from tweetnacl.

Key features:

- Zero dependencies (libc and C compiler are likely required though), so it
  could be easily used in embedded systems.
- Modern cryptography primitives (ed25519, blake2 and sha512 namely).
- Ability to encrypt files with the same keys using curve25519 based cryptobox.
- Protecting secret keys by passwords using PBKDF2-BLAKE2 routine.
- Asignify can convert ssh ed25519 private keys to the native format and verify
  signatures using just ssh ed25519 public keys (without intermediate
  conversions).
- Asignify provides high level API for application developers for signing,
  verifying, encrypting and keys generation.
- All keys, signatures and encrypted files contain version information allowing
  to change cryptographical primitives in the future without loosing of
  backward compatibility.
