Added more functional tests, fix bugs discovered.

* Fixed the formatting of command line logging of strawboss workers.
* Fixed a bug in the (de)serialization of log levels in the strawboss service
  config file.
* Pulled `parseBuildStatus` logic out of `loadBuildStatus` so that we could
  parse a JSON that didn't come from a file.
* Added `parseRun` for Run objects.
* Moved `/ping` to `/service/debug/ping` for symmetry with
  `/service/debug/stop`
* Added functional tests of full builds.
