Convert mon-pick data to a more readable scheme.

Instead of a base level and a rarity, which then use a ridiculously obscure
algorithm to accept or reject monsters, the new data includes:
* minimal depth the monster can be found on
* maximal depth
* rarity at the center of the range
* distribution type (flat, a linear triangle, something halfway between the
  two)
* the monster's enum

The results should be the same, with very minor differences:
* distributions within allowed range are approximated by one of three shapes
  (FLAT, SEMI, PEAK), this shouldn't produce noticeable differences
* effective rarity has been shoehorned into a 0..1000 range (out of 0..10201),
  using div_rand_round().  There's a number of monsters with 35/10201 rarity
  which ends up as 3 or 4, and strings of monsters of the same rarity end up
  randomly perturbed.
* the once-in-the-life-of-universe chance to generate a monster outside the
  -5..+5 range is gone, you can now set arbitrary ranges and they're absolute.

There's no actual code to use this data yet, merely an emulation of the old
functions.  It looks like ZotDef applies some complex rules to the monster's
depth, it may take some thinking about how to convert it.
