Move event handlers to the form element instead of button clicks

[DennisRas]

This would allow the user to press enter when submitting a form.
I'm sure in some way, this would also add some additional points towards better accessibility.
And for mobile users they can use the "Move to the next form element" button with some keyboard apps which would submit the form at the last input.
