Feature: Ability to change dice size of monsters

[DiversionManager]

While the default method to calculate a monster's hit points is by rolling a number of d8s per monster level (LV) and adding its CON modifier, it would be great if the system allowed for changing the dice size of a given monster to d4s, d6s, d10s, or d12s!

A range of sizes allows for homebrewing things like dice size being correlated to monster size and powerful-but-squishy wizards.
