TOON: Migrate Pathfinding Path Buffers to Common::Point.

This removes the need for i32Point, which used int32, instead of the
int16 of Common::Point. Since the co-ordinates passed in are in int16,
this is safe. Tested with no regressions.

Also, removed return value from walkLine function as it always returned
true.
