* Corrected Icewall skill to be closer to official behavior (part of bugreport:38)

- now works on occupied squares (previously it disappeared)
- now you can walk out of an icewall square (removed code that blocked pathfinding if the origin cell was of a nonwalkable type)
- added back the hack where mapcell changes are broadcast to whole map (prevents client from leaving the cells non-walkable if you warp away)
