LP1903767 - Bootstrap Opac: Make other formats and editions more visible.

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 makes the
header tage and <h2> tag consistent with other header tags.
3. Resizes <h2> tags.
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 that contains Place Hold.

For Testing:

1. Find a record that contains other formats and editions.  In concerto
record #71 contains other formats and editions.
2. Notice that you have to click the More Details button to view the Other
Formats.
3. Apply the patch.
4. Other Formats and Editions now appear under the Available Copies and
Holds heading.  You no longer have to push the More Details button.
