* General cleanup of Teleports, Crossings and Child agents. They are now in the new AgentTransferModule, in line with what MW started implementing back in May -- ITeleportModule. This has been renamed IAgentTransferModule, to be more generic.
* HGSceneCommunicationService has been deleted * SceneCommunicationService will likely be deleted soon too
