Comment 10 for bug 1067823

Added Andrea's and my signoffs to the branch and added a commit that:

* Displays the genre facet by default
* Removes the 659 tag from the index definition and from the display of genre links on the record summary page. The 659 had previously been included in those genre links, but is an unassigned MARC field.
* Updates the release notes to reflect those changes.

Branch is in the working repo at http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/kmlussier/lp1067823_genre_index
