------- Additional Comments from Daniel Bates <dbates at webkit.org>
Changed to raise an exception in ProcessAttachmentsMixin, and ProcessBugsMixin
if we are running in non-interactive mode.
Added comment in PrepareChangeLog and just let the BugzillaError exception
bubble instead of explicitly catching it.
