API proposal: currentRefinedValues widget

[Jerska]

Follow up of #112 and #378:

search.addWidget(
  instantsearch.widgets.currentRefinedValues({
    container: '#current-refinements-list',
    cssClasses: {root, header, body, clearAll, list, item, link, count, footer},
    attributes: [ // Optional, if not specified, takes all of the facets
      { name: 'category'[, transformData: function (data) { /* ... */ return data; }]},
      { name: 'brand'[, transformData: function (data) { /* ... */ return data; }]}
    ],
    templates: {
      header: '',
      item: '' + // Called with this.facets[current_facet.name].transformData({cssClasses, facetName, name, count})
        '{{ name }}' +
        '<span class="{{ cssClasses.count }}">' +
        '  {{ count }}' +
        '</span>',
      clearAll: 'Clear all'
      footer: ''
    },
    clearAll: 'after', // [true, false, 'before', 'after'] (true == 'before')
    hideContainerWhenNoRefinements: true
  })
);

I've changed facets with attributes since it should also handle _tags.

Moving to "next" (1.1.0)

@jerskouille that's done, right?
