this parallels the same code in the breakpad version of the socorro submitter.  Since this app was originally intended to be run ad hoc from the command line, the 'print' gives feedback about the success or failure of the submission.  In the breakpad version, this returns the crash_id assigned by the collector. I've used this in the past to pipe crash_id to other linux command line apps.  For Bixie, it is less important as the Bixie collector doesn't return the assigned crash_id.
