Fix passivetotal service.

No need to use headers anymore.

"apiKey" is renamed to "apikey" in the submission, so name variable
accordingly.

Don't need to do a json.dumps() on the params anymore as they now MUST be
put in the URI as parameters, not in the body.

The resulting data has also changed slightly, so adjust processing there.
Merge branch 'master' into distributed_services
