Bug 23518: Problem with borrower search autocomplete

This patch fixes a bug introduced by my patch for Bug 23405: Keyboard
navigation of patron autocomplete results was broken because I
incorrectly assumed that the autocomplete "select" action was redundant
because keyboard navigation would trigger the selected link. It doesn't!

This patch adds the "select" action back to the autocomplete
configuration, explicitly defining a redirect to match the URL which is
followed if the user uses the mouse to click a result.

To test you should have a patron in your database which has no card
number. Make sure CircAutocompl is enabled.

- From the circulation home page, type a patron name in the "Check out"
  form and wait for autocomplete search results to display.

- Making a selection from the autocomplete results should work by
  clicking with a mouse OR using the arrow keys and TAB or ENTER.

- Test with patrons with and without card numbers.
