/**
 * Replacing inputs of types 'button' and 'submit' in order
 * to get the correct styles in non-Mozilla browsers.
 * The 'applyFix' method searches through the entire document
 * for all input elements. Then it alters the elements of type
 * 'submit' by replacing them with a 'hidden' input and adding
 * an anchor tag with rel='formSubmit' and the id of the
 * element as the target href.
 * Additionally a handler is added to the ClickHandler. This
 * handler will recognize the new type of links, search for
 * the target input-element, enable it and submit the form.
 * By enabling the element it's value will be added to the
 * submition of the form, just like it would have been when
 * you had clicked on the 'submit' button.
