change in examples/djopenid/util.py normalDict function

[ashok-raavi]

as per the django docs, http://docs.djangoproject.com/en/dev/ref/request-response/#django.http.QueryDict.iteritems

QueryDict.iteritems will returns the last value if the key has more than one value,

the return value of normalDict function in examples/djopenid/util.py has to be
return dict((k, v) for k, v in request_data.iteritems())

It should be even bit more complicated to fulfill conditions from protocol.

def normal_dict(request):
    """
    Converts a django request arguments (MultiValueDict request.GET, request.POST) into a standard python dict 
    whose values are the last value from each of the MultiValueDict's value lists. This avoids the OpenID library's 
    refusal to deal with dicts whose values are lists, because in OpenID, each key in the query arg set can have at most one value.
    Also converts keys from unicode to string, so they can be used as arguments in functions.

    If request method is POST silently throw out OpenID-like arguments from GET see
    U{http://openid.net/specs/openid-authentication-2_0.html#rfc.section.4.1.2}
