Subject: [PATCH] javascript to toggle record selection status

- checkboxes now show up only when JavaScript enabled
- toggling a single record checkbox adds/removes it from temporary list
- toggling the select all checkbox adds/removes all records on the page
- legacy add/remove links when a patron is not logged in tweaked to
  always be present, but to have visibility controlled based on checkbox
  chanegs
