- Added an alternate path searching method for non-stacking mode.

- Allowed pc_setpos to place players on top of cells that are stacked in CELL_NOSTACK mode.
- Fixed a missing break that was making Heal, Resurrection and some others become attack skills x.x'
- Fixed a logic bug in the mob-walk code that was making them get stuck and not move (triggered quite often when the cell no stack mod is enabled)
