SASVIEW-957 logging changes (#158)

  • rework XStream to continue to write to stdout/stderr alongside redirection; make logging level setting consistent; make log configuration more consistent
  • rm XStream; QT signal in QtHandler? logging handler; only logs in Log Explorer (no stdout/stderr)
  • no need to change handler level
  • use QTextBrowser.append to facilitate auto-scrolling in the Log Explorer
  • modify logger unit test to reflect changes (passes)
  • Property mode set to 100644
