Fix for Bug 3347 - Inconsistencies with tables in opac-shelves.tmpl

Changes to list contents view to make it consistent with search results

My intention is to make the OPAC more consistent in the way it displays
lists of items, whether it be in search results, lists, etc. This patch
adds data to the list contents output and reformats it to that end.

The other significant change is the removal of jQuery table sorting.
Since list contents are both sorted and paginated on the server
side. Adding a client-side sort to one page of many doesn't make sense.

Other changes include:

- Change "Your lists" to "Your private lists"
- Remove "sort by" column because it seems unnecessary
- Adding logic to control display of count (item or items
  rather than item(s)
- Styling pagination bar and placing at the bottom of the page,
  consistent with other instances of pagination navigation
