Bug 13599 - Add patron cardnumber to self registration confirmation

Some libraries wish to display the patron's cardnumber on the
confirmation screen for patron self registration, rather than make the
patron locate it his or her cardnumber by logging in and browsing to the
personal details page. We should also add ids to these fields for easy
css styling/hiding.

Test Plan:
1) Apply this patch
2) Ensure that autoMemberNum is enabled
3) Self-register a new patron
4) Note confirmation screen now displays the patron cardnumber
