Made WebFeatureService be a new-style class.
Updated SSURGO test to include timeout (the new WFS default timeout
of 30 seconds caused the test to fail)
Updated test to reflect behavior of owslib.feature.WebFeatureService_.getGETGetFeatureRequest()
Reverted test to previous behavior for getGETGetFeatureRequest
Moved timeout from getfeature call to constructor call
