Bug 16386 - Replace the use of "onclick" from patron card creator templates

This patch removes the use of "onclick" from several patron card creator
templates. Events are defined instead in JavaScript.

Also changed:

- Patron search pop-up window is now slightly larger because I found it
  never quite large enough to prevent horizontal scrolling.
- Replaced "Borrower" with "Patron" in a couple of places.
- "Add" link in patron search pop-up is now styled as a Bootstrap
  button.
- Removed Bootstrap styles from some submit buttons.
- Some Font Awesome icons were made using the invalid element
  <icon></icon> instead of <i></i>. These are corrected.
- Fixed some other HTML validation errors.

To test, apply the patch and go to Tools -> Patron card creator.

- Choose New -> Card batch.
  - Click "Add patrons" and perform a search for patrons in the pop-up
    window.
  - Click the "Add" button. The corresponding borrowernumber should be
    added to the textarea in the parent window, and a message should
    appear at the top of the pop-up window confirming that the patron
    has been added. (Note: This patch fixes a version of Bug 13041 which
    prevented the "add" button from working on patrons whose name
    include an apostrophe).
  - In the parent page, in the list of patrons you added to the batch,
    confirm that clicking the "Delete" link triggers a confirmation
    dialog. Test both confirming and canceling.
  - Confirm that clicking the "Export" button next to an individual
    patron triggers a modal window.
    - In the export window, confirm that the "Cancel" link works to
      close the modal.
    - Click the "Export" button again and then the "Export" button in
      the modal.
      - Test that the "Done" button works to close the modal.
- Choose Manage -> Card batches.
  - Test the "Delete" and "Export" buttons as described above.
