Z3c.etestbrowser

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

- Added ``z3c.etestbrowser.wsgi.ExtendedTestBrowser``, a variant that can be
used when the test layer was set up using ``using
zope.app.wsgi.testlayer``.

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

- Took ``zope.securitypolicy`` refactoring and ``zope.testing.doctest``
deprecation into account.

- Added ``z3c.etestbrowser.browser.ExtendedTestBrowser``, a variant that
speaks HTTP instead of directly talking to the publisher talks to the
publisher, see `Using testbrowser on the internet`_.

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

- Added doctest to `long_description` to show up on pypi.

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

- Updgraded pacakge to lxml 2.2.

- Fixed bug with `normalized_contents` which would break the `open` function
of test browser if content wasn't parsable as HTML/XML.

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

- Added `normalized_contents` attribute that reindents and normalizes the
etree structure of a document and allows easier to read HTML/XML examples in
doctests.
