- Added a read-only ``domain`` property to ``BaseRequest``.  This property
  returns the domain portion of the host value.  For example, if the
  environment contains an ``HTTP_HOST`` value of ``foo.example.com:8000``,
  ``request.domain`` will return ``foo.example.com``.
Add strings_differ for SignedSerializer
Add SignedSerializer
Add CookieProfile class

This object can be used in conjunction with a Request object to parse
information from a cookie, or it can create new cookies that are
automatically set on a response or just passed back to the user.
Add SignedCookieProfile

Uses an secure HMAC to sign cookies before sending them to the web
browser, this way if it is tampered with it is easy to verify.
Add tests for all the new stuff

Do note that currently tests seem to fail under Python 3.2 and Python
3.3.
- Make tests pass on Python 3.

- Treat serializer as a single entity instead of having separate serialize
  and deserialize functions.

- Don't have a "_default_serializer" class attr as the only reason to do
  this would be if it were overrideable and it's not because it's
  underscored.

- 79 columns.

- Add changelog entry and update docs.
doc generation fixes
loads takes binary, not native
- Cookies generated via webob.cookies quoted characters in cookie values that
  did not need to be quoted per RFC 6265.  The following characters are no
  longer quoted in cookie values: ``~/=<>()[]{}?@`` .  The full set of
  non-letter-or-digit unquoted cookie value characters is now
  ``!#$%&'*+-.^_`|~/: =<>()[]{}?@``.  See
  http://tools.ietf.org/html/rfc6265#section-4.1.1 for more information.

- Cookie names are now restricted to the set of characters expected by RFC
  6265.  Previously they could contain unsupported characters such as ``/``.
typo
- Older versions of Webob escaped the doublequote to ``\"`` and the backslash
  to ``\\`` when quoting cookie values.  Now, instead, cookie serialization
  generates ``\042`` for the doublequote and ``\134`` for the backslash. This
  is what is expected as per RFC 6265.  Note that old cookie values that do
  have the older style quoting in them will still be unquoted correctly,
  however.
