This patch does the following:

1. Moves "Other Formats and Editions" below # of holds and available items.
2. Changes "Other Options" to "Other Formats and Editions" and made the header
 tag and <h2> to be consistent with the other header tags.
3. Resizes <h2> headers.
4. Removes bullets and changes the margins of some of the table/list displays
 under the <h2> headers.
5. Fixes the alignment of the button group (Place Hold, Remove from basket)

For testing:
1. Find a some records with other formats and editions.
In concerto record #71 contains other formats and editions.  You could also
copy a couple of existing records and make some changes to create other
formats and editions.  For example, add a language code, or change the publication date.
2. Notice that you have to click on the More Details button in order
to view the Other Formats.
3. Apply the patch.
4. Other Formats and Editions now appears under the Available Copies and Holds Headings.
