ToME: the Tales of Maj'Eyal

When spawning quest items onto the map we sometimes get them placed in unreachable (except by digging) locations. Common example: Lore required for secret Trollmire trapped by trees. (Yes you can dig them out, but new players will never know and will miss out on fun content).

Solution: Check an astar path to portal on placement.

I think this is almost the only case, and it makes a fun challenge to figure it out. Not everything should be completely obvious IMO.

Digging trees doesn't even make sense. Especially as there's a quest for finding the treasure, this doesn't seem ideal to me.
