django-ucamwebauth uses OpenSSL.crypto.verify, which was introduced in
python-openssl 0.11, which is newer than (say) SLES 11 has in it.

This follows <https://wiki.cam.ac.uk/ucs/Platforms_packaging_guidelines>
and expects that you'll be building a package like this:

python setup.py sdist -d .
rpmbuild -ta django-ucamwebauth-1.0.tar.gz

No clever version-number handling at present.

This adds significant useful functionality.  In particular:

 * Newly-created users can be configured by overriding the configure_user
   method and have their names modified by overriding clean_username.

 * The model used for users can be overridden by setting AUTH_USER_MODEL.

 * All of the permissions-checking functionality of ModelBackend survives.

It also reduces the amount of ucamwebauth-specific code substantially.

A backward-compatibility hook is included to ensure that
UCAMWEBAUTH_CREATE_USER is honoured and defaults to False.

Required because debian/rules explicitly invokes markdown_py.

Specifically:
 * Construct the request message using urllib.urlencode rather that doing
   it by hand.  This saves a lot of invocations of urllib.quote and
   correctly quotes spaces.
 * Construct the "params" field of the request message using another
   instance of urllib.urlencode.  This ensures that it is correctly
   quoted.
 * When interpreting an encoded response string, pass every field
   through urllib.unquote.  This ensures that they are correctly
   unquoted.

Also added support for showing custom errors for status codes different
from 200.
