RFE: Support for list sources

[atodorov]

From the example docs:

    weatherdata = \
        DataPool(
           series=
            [{'options': {
               'source': MonthlyWeatherByCity.objects.all()},
              'terms': [
                'month',
                'houston_temp',
                'boston_temp']}
             ])

I'm storing some data in Amazon SImpleDB and retrieving / working with it as lists of dictionary objects. At present it is not possible to use these lists for the source parameter in Django charts. Please add support for that (i.e. do not require QuerySet, Manager or a Model.

See #35 (comment) for information why this isn't easy to implement.
