streamline behaviour of component (trapped) forms with multiple submit buttons
this is because jquery can't know what button was pressed when the submit event is triggered. We circumvent it adding an hidden field before triggering the submission BTW: don't know why the commit seems huge. I just changed a bit the trap_form function to handle the corner case and streamlined what disableElement, enableElement, disableFormElements, enableFormElements do, along with formInputClickSelector
