Bug 13235 - Revise layout of patron search form

Bug 9811 (Patron search improvements) reversed the layout changes made
by Bug 10153. This patch returns to the form to its "stacked" layout.

To test, apply the patch and navigate to the Patrons home page. Expand
the hidden search fields in the search header and confirm that the
layout looks correct. Perform some searches and check that the results
are correct and that the modified search fields retain their state.

Note: This patch contains indentation changes, so please diff
accordingly.
