Based on #238

Add ability to pass regexp in `.htmlhintrc` file for matching attributes value.

Example:
```js
...
"id-class-value": {
    "regId": "^[a-z\\d]+([-_]+[a-z\\d]+)*$",
    "message": "The id and class attribute values must be in lowercase and split by dash or underscore"
},
...
```

Problem was in parsing config file by `JSON.parse`. We can not correct pass `regexp` into json schema. Only `string`. And this `string` after parsing is `string` too.

I just check input data. If it is not regexp then create `new RegExp` instance from input string.

Used Object.keys instead of Object.values because it is not supported by nodejs before v8.
