New waypoint type - use tile(x,y,z)

[LukeFisher]

A simple feature which could simplify many things such as the yalahar gates or walking through level doors.

Self.UseItemFromGround(x, y, z) --Returns the id of the item it found and used

[Raphael]

I might be wrong, but I believe that's exactly what 'Ladder' waypoint does.
