Yet another Gehennom revamp.

I took some inspiration from my last dNetHack game where I was able to
ascend (first time!) - its Gehennom is fairly random. The player won't
encounter the same demon lords/princes everytime, it's randomized, which
gives the endgame much more 're-playability'. This is my attempt to do
the same thing, EvilHack style. Here's the summary:

* Instead of encountering all eight demon bosses, the player is only
guaranteed to encounter four (Orcus plus three others)
* The other three demon boss lairs are divided into three tiers, with
each tier randomly picking from a pool of maps to load
* The map chosen does not determine the demon boss the player will
encounter - the demon bosses are also split up into three tiers (four
demon bosses per tier)
* Each tier is progressively more difficult than the last:
  - First tier: Juiblex, Baalzebub, Geryon, or (new demon lord) Baphomet
  - Second tier: Dispater, Yeenoghu, (new demon lords) Lolth, or
    Mephistopheles
  - Third tier: Asmodeus, Demogorgon, Tiamat, or (new demon prince)
    Graz'zt
* Both demon lords and princes have increased hit points
* Two new maps (demon lairs) were added (pulled the templates from
Splicehack and heavily modified them), and a few existing maps were
modified (notably Asmodeus level and Orcus town)
* A new room type was added (lemurepit) to go with one of the new demon
lairs
* Since Tiamat was pulled from the Caveperson quest, she has been
replaced with a new quest nemesis - Annam (Father of all Giants)
* Various tweaks and adjustments to existing demon lords/princes

There's more to do here (especially with Lolth), but I was at a point
where I needed to commit before I started to forget some of the earlier
edits :) These changes will hopefully make the endgame more fun,
interesting, and challenging.
