Fixes ergo-services#246 Changed mode from gen.ApplicationMode to int32 with atomic operations. Changed reason from error to atomic.Value for thread-safe access. This fixes the race between stop() and terminate() during shutdown. Also fixed race on state field in registerAppRoute() by using atomic load.
