changing accession memer query to use is_part_of so that large collections do not blow up the solr query
Adding open xml office mime types to the list so that derivatives get displayed for them
removing related file from the GF show page since this really slows down the page and the accession shows them all.
Adding back in the update accession after_filter.  Not sure why it was removed...
Cleaning up to use the collection relationship instead of the batch relationship as all the files may not be updated in one request.
