stat spells--update

[Peter Mardahl <peterm@soda.berkeley.edu>]

  I just gave Mark a set of patches to the stat spell code which will do
the following:

  gettting up to stat 20 is easy.

  Getting past stat 20 is expensive in time and spellpoints.


  Here's how it works now:  you have a 90% chance of going 20-21,
80% 21-22, (or is it 22-23?)

  down to 20 or 10% to go from 29 to 30.

  If you want to max your stats out, you're going to pay for it in time
and sp.  Everytime youcast the spell it costs you sp, but you have
a decreasing chance of actaully gaining a stat as you go higher.

  It may take youmaybe 20-25 castings to get from 20-30 now, maybe more.
