Zope.app.security

------------------

- Changed mailing list address to zope-dev at zope.org, because
zope3-dev is retired now. Changed "cheeseshop" to "pypi" in
the package homepage.

- Moved the `protectclass` module to `zope.security` leaving only a
compatibility module here that imports from the new location.

- Moved the <module> directive implementation to `zope.security`.

- Use `zope.container` instead of `zope.app.container`;.

------------------

- use zope.browser.interfaces.ITerms instead of
`zope.app.form.browser.interfaces`.

------------------

- Bug: It turned out that checking for regex was not much better of an
idea, since it causes deprecation warnings in Python 2.4. Thus let's
look for a library that was added in Python 2.5.

------------------

- Bug: The `gopherlib` module has been deprecated in Python 2.5. Whenever the
ZCML of this package was included when using Python 2.5, a deprecation
warning had been raised stating that `gopherlib` has been
deprecated. Provided a simple condition to check whether Python 2.5 or later
is installed by checking for the deleted `regex` module and thus optionally
load the security declaration for `gopherlib`.

------------------

- Feature:
`zope.app.security.principalregistry.PrincipalRegistry.getPrincipal` returns
`zope.security.management.system_user` when its id is used for the search
key.

------------------

- Initial release independent of the main Zope tree.
