Description

If a srs of a layer does not have a srid it should return None instead of throwing a Type Error.

I am using this dataset: http://www.eng.hctx.net/gis/Shapefiles/ZIP CODE.zip 

>>> from django.contrib.gis.gdal import DataSource
>>> ds = DataSource("/home/osc/data/zipcode/zipcodep.shp")
>>> layer = ds[0]

In [40]: layer.srs.srid
---------------------------------------------------------------------------
<type 'exceptions.TypeError'>             Traceback (most recent call last)
