[Featureserver] Service type does not support adding features

The '.gml' here says "I'm uploading GML." The GML service is output
only. So it fails and complains. If you change the '.gml' to '.json', it
will work. 

(Note that the above example is not valid GeoJSON, which is the
default_service in the config as of 1.07. You'd need to drop the extra 
'[]' around the coordinates. If you were to do that, you could just do
/all instead of /all.json.)
