lang/tauthon: Update to latest commit after 2.8.5

Highlights:
- email.generator: Fix handling of Unicode messages when not wrapping.
- Support compilation by GCC 14.

As these changes are very minor and upstream has not created an official
patch level for them, Tauthon's internal version/patchlevel has been
left unchanged at 2.8.5.

This is a maintainer update (olce.freebsd.ports@certner.fr).

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.

Keep this port deprecated, as it is a Python 2.7+3.X clone.
Nothing in the tree currently uses this port, but www/palemoon will

[NEW] lang/tauthon: Backwards-compatible fork of Python 2.7 interpreter with
Python 3.x features

------------------------------------------------------------------------------
Note this is not fully connected yet, and needs further changes to integrate
with flavors, addition to Mk/Uses/python.mk (or some equivalent USES=tauthon)
that may need discussion first, for instance, on the package name prefix.

This is committed to serve as a common test bed and for experimentation.

Maintainer:	olce.freebsd.ports@certner.fr (Olivier Certner)

Tauthon is a backward-compatible fork of Python's 2.7.18 interpreter with new
syntax, builtins, and libraries backported from Python 3.x.
