Honor .synced on data objects in all cases

Browse source 
Previously, if .synced was already true, setting it to true and saving
would result in .synced == false unless skipSyncedUpdate was passed. Now
the value assigned to .synced is always used on the next save. If the
value hasn't changed and no other values have changed, a save will be a
no-op.
