First stab at setting up priority styling:

- Can include priorities on rule by rule basis
- Should be broken out and added to config
- Setting then would be on per rule basis, e.g.

```js
HTMLInspector.inspect({
useRules: ["some-rule-name", "other-rule-name"],
prioritize: [{"some-rule-name":"high", "other-rule-name":"medium"}],
// etc... (or something...)
```
