Enhancement: Reconsider Accessions module columns/sort options in the UI

In AtoM's user interface, the Accessions module (under Manage > Accessions) displays and allows sorting for the following four fields: Accession number, Title, Acquisition date, and Updated.

These fields do not provide enough information do be able to sort effectively for organizations that have hundreds of accessions to scroll through from a single transferring body. It would be useful to include "Dates of Creation" and "Extent" in this table (and in the sort options) as well.
