Non-Firefox browsers dispatch "click" on descendants of <button>, which breaks
the submitHandler logic that adds a hidden field with the name and value of the
submit button (since it is not included in the submission if it did not
initiate the submission, which might be the case when using form.submit in
submitHandler and returning false). submitButton is instead a descendant of
<button> and the hidden field does not compensate for the lack of an actual
submit button.
This would fix crbug.com/668524 and make submitButton an actual button.

* Fixed a submitButton regression
Instead of returning a DOM element, a jQuery element was returned.
Changed to return the original element in the target is already a button case.
* Simplified the button with descendants support
Instead of looking for the parent or ancestor of the target,
just used the currentTarget property.
* Added another test
Devised by @Arkni.
If a previous element is already invalid, the the check of the current element
is never done and the current element becomes always valid.
Closes#1816, #1805.
As of now the signature of `validator.defaultMessage( element, string )`
is deprecated. Use `validator.defaultMessage( element, object )` instead
where objet is defined as
```
object = {
method: "method name",
parameters: "the given method parameters"
}
```
