Assorted fixes for minor issues with ZODB History tab:

1. When viewing history of a website or websection in the "backoffice" interface, clicking on View ZODB History does not keep the ignore_layout:int=1 request parameter that forces displaying the forms in the View skin selection.
2. Fix using ZODB history for documents with binary properties, such as data property on images and files. Instead of failing with unicode error, just display "(binary)".
3. Put the link field in center group, forms with only fields in left group and nothing in right group have a border only on the left side.
