* Added DefaultNotificationService and DefaultUserNotificationService
implementations that can be used by subsystems that want to have a pretty standard service. Only the latter is really complete, though. * The notification manager is now available earlier in the boot process. * Added notifications to teams/ports (only add/remove). * The network notification implementation is now using the DefaultUserNotificationService. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29543 a95241bf-73f2-0310-859d-f6bbb57e9c96
