Adjusted more characters that spawned with cursed grade weapons.

Readjusted a lot of things. Among them the rarity of finding cursed and bandit gear on characters and vendors.

Since damage modifier of gear is dependent on the skill and the item itself, I made bandit more of the 'lesser' damage but higher buff gains to atk/def, and cursed as a means of higher cut, but greater atk/def (glass cannon) skewed setup.

Remembered that weight has a impact on damage values, so toned it down a bit so it's still greater than normal, but usable.

Adjusted rates so that cursed weapons aren't insanely plentiful, readjusted cursed weapons because min cut damage doesn't perform as close to as I like it.

Updated Cursed and Bandit manufacturer and grades to be available ingame.
