Smaller version of the saving throw code.

By Rob Baumstark

Here's a much smaller version of the saving thow code that was new in BPL13.
It will return almost the same values as the old array did (within 2/90),
but allows for much easier additions and modifications.  Feel free to use it
anywhere, so long as you leave the comment with my name in it (You don't
need to add it to the credits or anything, but it would be nice :)
----- Begin Code -----
/*
* Saving throws for:
* MCTW
*   PARA, ROD, PETRI, BREATH, SPELL
*
* Drop in replacement for Circle BPL13A saving_throws() by Rob Baumstark
*  Small function that replaces about 1000 lines of array.
*  Now automatically adjusts to the number of levels, and is easier to
*  adjust the ranges, or add new classes or saving rolls.
*
* Do not forget to change extern declaration in magic.c if you add to this.
