** Accessibility of offline status

  Offline status should be indicated in the MavenSettings instance, since it
  can conceivably be set from either the settings.xml or the command-line.

  In the event the '-o' switch is the impetus for setting offline mode, this
  should result in modification of the active profile in the MavenSettings
