#228 Data unavailable to reviewers

[William Piel]

As a result of new changes to our authentication system (in which PURLs are only remapped for data that are "public"), we have lost the ability for reviewers to download/inspect data ahead of publishing. For example, this URL:

http://purl.org/phylo/treebase/phylows/study/TB2:S10899?x-access-code=76a402a5dd67ebc2599e072d18f368c1&format=html

... contains an x-access-code parameter, which is supposed to give special access to the data even if the data are not yet public. The new authentication system does not handle this properly for reviewers. All the download links that use PURLs need to be made downloadable when the x-access-code is used.
