Enhance Product Option Values

[alecritson]

Currently option values, are stored against variants, are quite basic and a bit brittle to work with. It would be good to enhance these in places to make them a bit more flexible and improve the way they can be interacted with.

Add attributes

It would be handy if you could attach attributes to a value, for example you might have the colour "Blue" as a value and what to either store an image or a hex code against it.

Another example if you may want to display a certain icon/image for that value.

Add a handle to values

Currently the only way to match against values is to take the translated name and do a full text match, I feel like this could be problematic in the long run and lead to brittleness. It would be good to have something like a handle the developer could assign so it's consistent.
