/*:@plugindesc Modifies the database drop functionality to be a percent instead of 1/N.
@author J

@help The plugin makes it so that the number you enter into the database is now the
        percentage chance of the item dropping instead of 1/N chance, where N is the
        number you entered in the database.

        Additionally, to accommodate the possibility of decimals, you can change the
        setting so that it reflects off of either 100 or 1000 point scale. 100 scale
        is as you know it: enter 54, and it will be 54% chance of drop. 1000 point
        means that if you enter 54, it will be 5.4% chance of drop, 547 will instead
        be 54.7% chance of drop. Default will be 1000, but you can change it to 100
        if you want.

        NOTE: obviously, you can change the scale to whatever you want, but be sure to
        take a look at the math in the function if you do to make sure you understand
        what you are doing to the numbers!

@param dropScale
@desc 100 or 1000 depending on if you don't or do need decimal chance drop rates.
@default 1000
