Automatically apply ability score bonuses to armor.

For example, let's say we have the following:

              <vellum-monster
                id="monster"
                name="Monster"
                named="true"
                size="Small"
                type="fey"
                alignment="chaotic neutral"
                baseAc="10"
                armor="natural armor"
                hit-die="2d6 - 2"
                speeds='["30 ft.","swim 30ft."]'

                str="10"
                dex="14"
                con="8"
                int="13"
                wis="10"
                cha="15"

This would display as as an effective/actual AC of 10 (baseAc + Dex Modifier of +2).

This would need to be supported with a default ac attribute which allows users to ignore calculations and force the monster's AC.
