Pan Lord spell adjustments

 * Cut the high chance for teleport self and blinking. With the spell
   slot system no longer making it emergency only, it became highly
   likely for a pandemonium lord to randomly teleport whenever it wants.
   The use of teleport self also isn't particularly interesting here,
   and blinking is both extremely common and not necessarily helpful
   while forced as such.
   - In a much less noticable but significant fashion, I've removed a
     no-longer-necessary block on an extra chance to Dig (due to its
 * Replace some minimum-level spells in their custom spell lists with
   higher-level spells, either unused previously or tacked on much
   later on in an ugly, messy way. These spells were inherited from the
   code previously sharing functionality with ghosts, a concern no longer.
   The slim chances of Magic Dart, Flame Tongue, Freeze, Sandblast, Shock,
   Sting, Pain, Ensorcelled Hibernation, Summon Small Mammal, Call Imp,
   and Corona (listed twice!) have been replaced with, respectively,
   Quicksilver Bolt, Steam Ball, Smiting, Corrosive Bolt, Boltblink,
   Poison Arrow, Vampiric Draining, Sleep, Summon Vermin, Shadow Creatures,
   and Drain Magic / Poisonous Cloud.
   - For Quicksilver Bolt, Smiting, and Steam Ball, this is an added 1.6%
     chance more to see them while lowering the infinitesimal chances of a
     pan lord getting an excessive amount of spells. The other such listed
     spells were absent entirely, either from not existing when the list
     was first arranged or awkward connotations with ghosts or whatever.
     Pandemonium Lords will be marginally more scary, but the odds of most
     of the previous extremely strong spells (i.e. Torment, Hellfire,
     Fire Storm, Glaciate, etc) haven't been touched.
     ~ Also, there are still some very sad spells left: Throw Flame / Frost,
       Sticky Flame, and Mephitic Cloud are the obvious harmless ones.
       There's not many spells left to directly replace them with, and I'd
       rather defer figuring out if direct removal (and thus marginally more
       common much bigger spells) or other accessible gimmick spells would
       be solutions, if necessary, to those areas. I already feel lightly
       guilty for using rather rare Blinkbolt here (the raiju special.)
   - Also, a straight upgrade for melee-only sticky flame to ranged
     (once more, not that sticky flame means anything on pan lords),
     and from Twisted Resurrection to Simulacrum (for the Ds).
 * Resort these horribly messy lists. Ordered by level, then a vague schools
   list of Conj, Fire, Ice, Earth, Air, Poison, Necromancy, Summons, Charms,
   Hexes, misc. (Some monster-only spells have an ordering based on schools
   or levels hidden in the spell data.) I don't even want to begin to think
   of the implications of the scattered order of this list previously
   influencing ghost spell selections, and it's good it's no longer relevent
   for that.

Of course, with all this, the way it's all done is still absolutely horrific
anyway and much better refactoring / saner creation work would be nice. Just
fixing up a little bit of the current situation.
