Travel Message Handler. This contains a set of messages that are specific to different types of TravelConnector objects, to describe NPC arrivals and departures via these connectors when the NPC's are in view of the player character.

This base class implements the methods simply by calling the corresponding gLibMessages message methods.

The purpose of providing this variety of connector-specific handlers is to make it easy for individual travelers to customize the arrival/departure messages for specific connector subclasses. These messages sometimes benefit from customization for specific traveler/connector combinations; the easiest way to enable such granular customization is to make it possible to override a message per connector type on the traveler object.
