1. Changed default labels to Spanish.
2. Support a textFilter field to do a full text search of the results.
3. Allow a callback to notify an external listener of result updates. This can't be done with jQuery trigger like the other notifications as this only supports simple objects.
4. Display facet items in a select field. Because of this the click event handler for .facetitem only works in Firefox, instead now listen to the changed event of .facetlist.
