Changed the annotation display code to use the metadata MODS record for an annotation rather than the content MODS record (Which are identical).
Fixed the iframe code so that the BDR viewer's fullscreen buttons work.
Fixed the pages-for-person section on a person view--it was only searching by last name.
Undid previous thumbnail error-checks, and updated thumbnail URLS to proper BDR thumbnail service.
