Default geom_type attribute for GeometryWidget should be "Geometry", not "Unknown"

The default value for geom_type is "Unknown" whereas we expect it to be "Geometry".

Indeed, by default we rely on GDAL to set the geom_type attribute, and it returns an unexpected value :

>>> from django.contrib.gis import gdal
>>> str(gdal.OGRGeomType('GEOMETRY'))

In fields, we override explicitly his value, so the problem is hidden.

But IMHO the widget should behave nicely with default values, for example instantiated like this :

class BigMapWidget(BaseGeometryWidget):
    map_height = 1200

class GeomForm(forms.Form):

    def __init__(self, *args, **kwargs):
         super(GeomForm, self).__init__(*args, **kwargs)
         self.fields['geom'].widget = BigMapWidget()

Of course, this problem only applies to generic Geometry field types, and those are commonly used.

Eric, don't forget to link to your PR from the ticket and check "Has patch" so it's picked up for review.

Here's Eric's PR. It looks good to me but I'll let Claude or something more familiar with GeoDjango do a final review.

Eric, can you explain where the 102 number comes from in your patch? I'm not sure changing the OGR semantic is a good idea. I think we'd rather solve this in the forms/widgets layer. But I'm open to any other argument.
