Sketch/Control Weapon Stats

[asilverthorn]

WIP change to make Sketch/Control physical attacks use weapon stats.

Generally working, although the damage from Control still seems a bit too low, likely due to the difference in algorithm between character physical attacks and monsters.

Specifically, Damage = Level * Level * (Battle Power * 4 + Vigor) / 256 for monsters vs Damage = Battle Power + ((Level * Level * Attack) / 256) * 3 / 2 for characters. ref: https://gamefaqs.gamespot.com/snes/554041-final-fantasy-iii/faqs/13573 section 2.1

TODO:

• determine if the resulting damage numbers are satisfactory
• test other weapon effects (currently only tested Heal Rod, for which the sketched/controlled abilities did heal as expected)
• test Sketch/Control with caster Genji Glove/Sniper/Offering effects to make sure there's no oddities
