Set all documents to be published/not published

[M-C-McGrath]

This is a special case of https://github.com/TransparencyToolkit/LookingGlass/issues/83 where the document types (all of them), fields (to_publish), and values (Yes/No) are all preset. We just need "Set all documents to be published" and "Set all documents not to be published" buttons somewhere. This allows users to publish all documents by default and selectively filter out certain documents.
