Bugfix release.

There was a bad check against jQuery's inArray(), that made the deserialization from arrays fail on index 0.

This version fixes two use cases:

1. When there are return characters in a textarea and it's deserialized to JSON Object.
2. When deserializes a string (not an object) containing an array (for multiselect SELECT elements, or checkboxes).

Also, added a multiselect to the demo page.
