title: iPhone: stopMonitoringSignificantLocationChanges when app quits
body: <p>I want to stopMonitoringSignificantLocationChanges when the user is killing the app from the multitask bar (switch bar) like the Waze GPS App does.</p>
  
  <p>(i also want to cancel all LocalNotifications)</p>
  
  <p>the problem is, that after an application get's suspended, applicationWillTerminate doesn't get called.</p>
