Merged document should return empty hash not nil if there is no content to return
Clean up tests for external documents.
Always ensure document timestamps are set.
Sanitize and normalize documents when assigning, and don't update timestamp when nothing is being changed.
When assigning the document, ignore any key/value pairs that exist at the top level of the external document; ie. "unmerging" the document when assigning it, the reverse of Post#merged_document.
Upgrade to ActiveRecord 4.0 and sinatra-activerecord 1.4, which can replace the database tasks in bengler_test_helper. This also means using schema.rb instead of development_structure.sql.
Fix Post#visible_to? and Post#with_restrictions to check that identity is god in the correct realm.
Add support for PUT /posts/batch.
