textproc/UCD: bump PORTEPOCH after downgrade to 15.0.0

textproc/UCD: downgrade to 15.0.0

(pending better solution)

deskutils/gucharmap breaks because it requires 15.0.0 and refuses to
build with 15.1.0.

This in turn breaks x11/mate-applets.

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.

textproc: remove 'Created by' lines

textproc/UCD: fix fetch

Patch proposed by Daniel Engberg <diizzy@FreeBSD.org>:
- Only use HTTPS
- Instead of creating a new directory for each release use a subdir
- Grab license file from Unicode Han Database (Unihan) as they share the
  same and are both part of Unicode.
