[sugar] adding versions to journal/datastore

Say what? Maybe one could argue that this is the primary requirement
for the datastore, but the Journal is there primarily as a place of
reflection. The fact that the datastore has been problematic and that
the Journal is so underdeveloped relative to our goals may account for
the fact that feedback from the field has been so narrow.
