There is one thing that hinders setting information about version (tag,
comments, or other things) is that querying them is quite expensive
right now since the Archive needs to be fully parsed and each Document
version extracted from that archive.
I had the thought a long time ago that we need to replicate some
information about the different version in a table in the database. This
would be recreated when needed:

We would store in there:

- author of the update
- date of the update
- comment
- tag
- any other relevant stuff

This would allow to improve performance of version display since the
archive would not have to be parsed again and would also allow to query
to find out the most active users and all changes made by a user.
This would be a nice feature for 1.1
