Zope.password

==================

- Remove ``zope.testing`` dependency for tests.

- Update some copyright headers to comply to repository policy.

- Add ``zpasswd`` script formerly hold in zope.app.server. Contrary to
former zpasswd script, which used "Plain Text" as default password
manager, now SSHA is used as default.

==================

- Make security protection directives in ``configure.zcml`` execute only
if ``zope.security`` is installed. This will allow reuse of the
``configure.zcml`` file in environments without ``zope.security``,
for example with ``repoze.zcml``.

- Add "Password Manager Names" vocabulary for use with ``zope.schema``
and ``zope.component``, like it was in ``zope.app.authentication``.
It's an optional feature so it doesn't add hard dependency. We use
"vocabulary" extra to list dependencies needed for vocabulary functionality.

==================

First release. This package was splitted off from ``zope.app.authentication``
to separate password manager functionality that is greatly re-usable without
any bit of ``zope.app.authentication`` and to reduce its dependencies.
