Modal forms cannot be submitted in Internet Explorer because of the usage of form attribute

In Quizzard, modals make extensive use of the form-attribute on buttons to submit forms that the button is not part of. However, this does not actually work in Internet Explorer (https://caniuse.com/#feat=form-attribute), which breaks almost all Internet Explorer compatibility.

This should be fixed by wrapping the form around the modal body and footer such that the submit button is inside the form.

Update modals such that the form wraps around the modal body and footer.
