Cleanup after reconsulting file.
trying to force all facts to be retracted, as the player position is not correctly reset sometimes.
Better path finding
Nelarth now moves up and right on the grid, previously it would only travel down as far as possible then left into position 0,0, now there are clauses to help when the player moves above and to the right of her.
at the moment she is quite likely to trap the player onto one side of the map, need a way to make this less likely or something where she will not move that turn.
