AngularJS $http date parsing

Adds a response interceptor to $httpProvider that converts ISO 8601 date strings into Date objects.

HTML

<div ng-app="app" ng-controller="DemoController">
    <form ng-submit="go()">
        <label for="url-input">String returned from server</label>
        <input type="text" id="url-input" ng-model="form.url" value="lazio.coni.it/lazio/lazio/ricerca-societ%C3%A0-sportive.html?pagina=1" />
        <button type="submit">Go</button>
    </form>
    <div ng-show="url">
        <p><code>response.data.url instanceof String === {{isUrl}}</code>
        </p>
        <p ng-show="isUrl">Display using Angular's date filter: {{url}}</p>
    </div>
</div>
