Subject: [PATCH] Fixed Unstable Doors

Added code so that the links for Unstable Doors are handled properly by
DDTeleporter. Hurray! Also cleaned up some unused imports in the
BiomeGen classes and removed the RANDOM_DUNGEON link type - it was meant
for the dd-rift command but there is no need for it anymore.
