Bug 7067 [Follow-up: templates] allow patron self registration via the opac

- Adding simple style to register link on home page
- Adding unique ids to new pages and to blocks containing
  registration links
- Adding better page titles and breadcrumb links to some pages
- Correcting bug which meant incorrect message showed on registration
  page when OPACPatronDetails preferences is turned off
- Passing patron details to opac-memberentry.tt so that patron's
  name can be displayed in breadcrumbs
- Improving display in staff client of patron record updates
  waiting to be approved.
- Adding a sort by name to output of pending patron record updates
- Adding updated JqueryUI library files to include expanded widget
  options.

The changes in this patch require the addition of the jQueryUI
Accordion widget. Other pending patches are seeking to add
enough of the other remaining missing widgets that it seems time
to go ahead and add the rest.

Future submissions which add usage of these widgets will have
to be careful to make changes to Koha's CSS where necessary.
