Bug 22953: Markup warning in OPAC user summary template

This patch makes a minor markup change to the OPAC user summary template
(opac-user.tt) in order to quiet warnings from the HTML validator. The
obsolete name attribute on two links is removed in favor of class names.
The JavaScript has been modified accordingly.

To reproduce the problem you should have the AllowCheckoutNotes system
preference enabled. Log in to the OPAC as a user who has checkouts and
view the "your summary" page. Run the page through the W3C validation
service: https://validator.w3.org. Either by pasting in the URL for the
search results (if web accessible) or by viewing source, copying, and
pasting into "Validate by Direct Input."

This patch specifically addresses this warning:

 - "The name attribute is obsolete. Consider putting an id attribute on
   the nearest container instead."

To test, apply the patch and try again to reproduce the validation
errors. Those errors should no longer be present. There should be no
visible change to the page.

Test the process of adding or editing an note on a checkout. It should
work correctly.
