** 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
  instance, just as definition of the active profile from the command-line
