Bug 12478: Move mapping attributes to the join table

To make things consistent, the attributes of the mappings (sort,
suggestible, facet) should be moved to the join tables
(search_marc_to_field).
Indeed the search_marc_map could represent a mapping for several search
fields with different attributes. Before this change it was not
possible.
