Started using the ActiveFedora object in views rather than relying on Solr document.
Upgraded ActiveFedora to GitHub ref to get changes from PRs.
Merge branch 'develop' of https://github.com/duke-libraries/dul-hydra into develop
Simplified routes
Catalog controller #show action uses reify_solr_results to load AF object
Thumbnail controller uses Hydra download behavior
Downloads controller overrides #datastream_name
Use lazy reification in batch fixity check script (required updating active-fedora)
Upgraded active-fedora to 6.4.3. Fixes #216
Use ActiveFedora::SolrService.reify_solr_result(@document) to get object
Added #effective_permissions helper to calculate direct + inherited permissions
Added Permissions tab to show view
Added partial for Permissions tab content
Unwanted models configured in DulHydra::Configurable
Added AdminPolicy to list of unwanted models
Made initial changes to controller and required upgrade of hydra-head -- tests needed.
Added custom :discover ability to local Ability class, mimicking the way Hydra::Ability and Hydra::PolicyAwareAbility works.
ThumnailController#can_download? customized to require :discover permission on asset.
Tests added for direct and inherited object permissions.
