Idea: Save diffs

[jthomaschewski]

It would be a great addition if only diffs would be saved instead of whole copies of the original data. The problem with the current approach: As the history is embedded in the same document, document size is growing fast for documents with a lot updates and/or lot's of fields.

It would be sufficient to copy only changed fields - restore would be more difficult but shouldn't be too hard.

Another improvement for large documents would be saving the history into a separate collection. This would remove the whole overhead of embedded fields.
