LP1902265-Bootstrap Opac does not allow see/update per hold notification.

In the Bootstrap Opac:
Adds a Notify Method column to the patron's hold list.
Adds email, phone, and sms notifiction editing to the hold's edit screen.
Also, adds <label> tags to the existing form fields in the edit page for accessibility and some bootstrappy form elements to format the appearance of the form.

The SMS fields do not appear unless the Library Setting for "Enable features that send SMS text messages" is set to true.

To test work with the above OU setting off, and then on.
Place holds for a patron with and without an email address.
If a patron has a defualt SMS carrier, this carrier should pop up in the list by default.
