Added mechanism to have sync import jobs on import queue.
Review jobs are now sync with a controller waiting for 20 secs before returning.
If all reviews return earlier the controller extists earlier, too.
If one or more decisions took longer they are run in background till they are
decided and the the controller returns a error message for these imports
that the process is st still running.
