Title: [Form] New Email element and HTML5 Email view helper

Notes:
* Created a new "Explode" validator, to handle multiple email addresses (when "multiple" attribute is on). It's generic and works somewhat like a ValidatorChain. Although, I'm not sure I like the name "Explode".
* The Email element will check for the "multiple" attribute and either use a EmailAddress validator (if off), or a Explode Validator with an EmailAddress validator attached (if on).
