This patch installs a fully functional multiclassing system!  The concept
behind the multiclassing is:

  (1) Took ch->player.level to level_mage/cleric/thief/warrior, and
      defined simple look-up/set functions.
  (2) Yanked ugly tables: THAC0, Titles, & Guild Guard.
  (3) Implemented a THAC0 formula, Exp formula, & ROOM_GUILD_???? flags.
  (4) Yanked Level gain in gain_exp, left it in gain_exp_regardless for
      do_advance.
  (5) Reworked do_levels for a class arg.
  (6) *Biggie!*  Modified SPECIAL(guild) for the following:
        a. Look at RoomFlags ROOM_GUILD_???? for Guild's class.
        b. Besides 'practice', added 'gain' which gains a level in
           the Guild's class.  'Gain' added to interpreter.c too.


Easy to add levels to the mud:
  STEP 1. Increase LVL_IMPL/IMMORT.
  STEP 2. Refigure formulas for THAC0/Exp.  You might want to do this anyway.
            THAC0: (20 - GET_LEVEL(ch) / ###) <- change the last number
                                               1.00 will bottom out at 20
                                               1.25 will bottom out at 25
                                               1.75 will have a L30 THAC0 of 3  
                                               2.00 will have a L30 THAC0 of 5
           Exp: exp += i * ####; <- change that number for higher/lower
                                    increase in exp.  Remember though,
                                    Exp for the next level starts over 
                                    from 0.
