The Edit button for each Employee now opens its edit form in a modal. The form successfully updates the database if the new values are validated. However, the way it's setup causes wrong values to make the app behave incorrectly. To solve this, the form can't be sent to the Controller unless it has been successfully validated. TODO: add confirmation of successful updates; change employee creation to behave just like edit; make a viewer in the Department/Detail view for Employee/Detail; add a dropdown menu of options for Employees.
