Start implementing support for mutaplasmids.

* There's a new table `mutators` that has an FK back to a module, and links to an attribute ID with it's new value
* Fixes an issue in the item state where the "base" value showed the literal base value for the attribute, regardless of override / mutators
* If there is an override and a mutated attribute, mutated value takes effect
