Changed the function to use a Hashtable mapping dungeon types to their
respective lists so that it wouldn't be necessary to hardcode a
condition for each type. The code is much shorter now and we can add new
types with ease. The next stage will be to remove
weightedDungeonGetList, if possible, so that we don't have to construct
a list with duplicates just to have weights. The loop that repeatedly
inserted dungeons into that list has been removed anyway, but it
shouldn't affect anything since custom dungeon integration was broken
and weights were being ignored.
