Under Combat tab, make Armour Type mods editable

Currently, Armour Type autopopulates armour mods correctly.
However, when possessing Magic Armour(eg. “encumbers as AT’n’” where ‘n’ is a totally different AT from the base) one is not able to override the armour mod fields at all, which incorrectly parses combat rolls due to this.

Make armour mod fields editable, also, overriding whatever gets autopopulated or add a second line that overrides the first entries above it.

Will create mockups to show what I mean.
