This commit changes the way tours are automatically disabled when in
demo data.
Previously, an override of the assets_common template was applied by a
file loaded in the web_tour demo data, ensuring that the tours are
disabled when demo data are loaded in the database.
Now, a "tour_disable" boolean will be given to the session_info object
to determine whether the tour manager must be disabled, meaning that it
will automatically consume all registered tours.
This has been done to improve consistency in asset bundles declarations
by reducing them to the simplest possible templates.
