Improves patching of bounding boxes

As @benjwadams pointed out, ckanext-spatial checks bounding boxes by
looking if lat0==lat1 and if lon0==lon1 whereas before I checked the
lower left and upper right corners. This patch adopts the CKAN style of
checking lat/lon individually and if they match offset them by 1 meter.
(Distance may vary depending on latitude).
