[tracker/dbus-fd-experiment: 3/13] Add Steroids example client

[Adrien Bustany <abustany src gnome org>]

    Add Steroids example client
    
    This commit adds a steroids-sparql program. This program shows how to
    use the tracker_resources_sparql_query_iterate function to do a query
    and fetch the results. It does exactly the same thing as
    tracker-sparql -q.
