added new variables for !setup.txt

all go in [setup] section of the file)
MagicResistanceRate=20 (this is basicaly a variable used to indicate how good magic 'evasion' should be, the higher the less likely it'll fail)
PoisonResitanceRate=0 (this is kinda psn evasion rate, 0 = minimum (default like it is now) the higher the more poison will WORK)
FreezeRate=60 (this is the rate at which freeze will work when using regular wpn, the lower the more it will work, the higher the less)
PoisonRate=60 (same as with freezerate but with poison on hitting)
