[test] Make test_undo_api less random
The order in which hooks are run is not predictable if they have the
same 'order' attribute, which is the case for SetOwnershipHook and
SetInitialStateHook. So don't assume in_state will be set before
created_by.

RSS driven
----------
RSS is a pretty useful technology that can be widely used on this
site. Any set of data can be presented as RSS. You can then plug in
an RSS reader into that and follow the site activity. For example :
:raw-html:`<p><a class="reference"
href="view?vid=rss&rql=Any+X%2CM+WHERE+X+modification_date+M+ORDERBY+M+DESC+LIMIT+30"><img
alt="rss" src="data/rss.png"> latest changes</a></p>`
