Title: [Form] MultiCheckbox / Radio label attributes and hidden value options

* Added feature to specify label attributes for each option (necessary for Twitter Bootstrap form styles).
* Added option to include a hidden input with an "uncheckedValue" (similar to checkbox).

If these features should be in separate PRs, just let me know.
