Title: From DataSource to DataSet in SE renderer

Until now, we've used DataSource instances in the SE renderer while we were just using the DataSet API. Even if that's not a problem from a feature point of view, it's not optimal. Indeed, we won't be able to render DataSet...

That's fixed with this PR. I've mainly replaced all the call to DataSource with calls to DataSet, and tested it was OK. I've even add an example of use in CanvaSE, where I just produce a DataSet, using a compiled SQL instruction :-)
