More student forms

In addition to adding a few forms, I needed to add another checkbox to the entityform type for whether to send the admin a confirmation email.  We were deciding whether to send the email depending on whether the admin email address field was empty, but I need the admin's email address for other reasons, e.g. it's used for the "from" address in the user's confirmation email.  This necessitated several changes to the forms.module code.  Also I set the checkbox for the existing forms.
