App Engine 1.1.9 update breaks django 1.0. Monkey patch django to only check for SVN revision number when not running using dev_appserver. On deployed version this doesn't apply since we use django from zipped file.

hashlib module containing both hash algorithms. Here, we provide a common
interface to the md5 and sha constructors, preferring the hashlib module when
available.
