    [EVENTVWR] Add support for a command-line for the Event Log Viewer.
    CORE-12269
    - Add support for '/?' and '/l:' switches. The former displays usage
      information. The latter allows to specify an event log file to load.
      Also one can specify the computer name from which one wants to
      retrieve events for display (work in progress).
    - In EnumEventsThread(), move around the code that updates the
      application title and status bar, so that the selected event log name
      and loading status is always displayed first, while loading itself is
      in progress.
