Upgrade setuptools in the Docker container, fixing #277
Add various indicies to the Change model to speed up lookups
Add a diff API endpoint to /change/, which returns a unified
diff of the JSON representation of the changed object, from its state
before the given Change happened and its current state.
Also update the development docs to reflect the current release process
(most importantly the release PR).
