Monster AI Upgrade patch

Well, there are always long jumps, right?

Here are some of the ideas in that thread that I thought made sense.

Code:

FB    Misc
      Modify Own Data        08    (Stat)    (Value)
      Gain/Lose status       09    (00/01)   (Status)
      
      (Stat) is the same as the monster data byte in RAM
      
      (which means you can set/remove status protections,
       change elemental reactions, set LV, HP, MP, Def,
       Mdef, Evade, Mblock, Batpwr, Speed, Hit Rate, EXP,
       GP, Control attacks, Sketch attacks, Attack graphic,
       !Special attack, !Special attack graphic,
       Metamorph chance/items, on the fly!)
            
      This one is so incredibly powerful. With this, you
      can make monsters that level up, change modes,
      even monsters that empty out their Steal slots
      or their money by Throwing weapons/using Items
      or using GP Rain.
      I especially like the potential for Sketch: you
      could have a monster react to Sketch by
      changing their own Sketch commands.
      
      Or you could make monsters that give bonus EXP
      and GP if you defeat them in a certain way or
      within a certain time. The possibilities are huge.

      (Status) isn't the same as FB 0C/OD ["Gain/Lose
      status"]. That one normally sets both Status and
      Immunity, meaning it's "Gain unremovable status".
      While gaining removable statuses is normally done
      via spells, it might be useful to be able to do it
      silently.)

FC    If...                        
      Steal slot is empty    30    (Slot)     00
      Target is controlled   31    (Target)   00  
      Formation pack zoning  32    (Zone)     00
      Target Level >         33    (Target)   (Level)
      Target Level <         34    (Target)   (Level)
      
      * 00 = higher than, 01 = lower than
      (I think it only makes sense to check Self for
       Steal, so it doesn't need a Target byte)

      The pack zoning one is interesting but can be
       achieved with the normal "If monster is in
       formation #". It might be a way to have the
       same monsters behave differently in different
       areas without using up formation slots though.
