Documentation should cover setting up test DBs.

[technomancy]

I like how the tests run over each of the databases to which they can successfully connect. It would be great for contributors if the docs could just show a few lines for each DB of how to create the necessary users and empty databases.

I'm planning a complete overhaul of Lobos documentation and will certainly include this. One thing I'm still not sure about is how to handle the database drivers, I didn't put them in the project file because I didn't wanted to assume which database contributors would use, but I think that concern is not warranted as the tests already handle failed connections.
