Survivor)
Changed intro text for client

Changed intro text for client to indicate if server is still loading or
not.
Ambient AI to spawn only if player finished spawning.

Ambient AI should now only spawn once player has loaded instead of the
possibility of loading on spawn island.
Ambient AI Remove group vehicle

Despawning of AI should now also despawn their vehicle (if any member of
the group was in the vehicle at time of despawn).
