Thank you kindly, Nlin for a patch that:
Adds a new method to IClientAPI to allow adding message handlers for GenericMessages (of which "autopilot" is one). Part 2 adds a specific autopilot handler in ScenePresence.cs. 2) Removing unused variables and functions. 3) Simplifying the navigation logic in ScenePresence.cs. The original patch was somewhat complex because it included orientation logic for a future enhancement of orienting the avatar to point towards the direction being walked. Currently this isn't working, though, so I removed the orientation code, which leaves just the smaller and hopefully simpler-to-understand movement code.
