Added a Data Table row for the interface.

Hey All,

Overall this is a minor addition. Exposes the more static members of the interface to a DataTable struct so people can set up data tables on how they'd want their NPC to be used. It's minor but allows the flexibility of using a DataTable while keeping the API clean.

The alternative to this might be somehow creating a hook in the interface to grab a DataTable handle and writing our own implementations of this interface. Still, it feels like this allows for more flexibility.

Thanks, Michael Brune
