    google: Add support for tasks
    
    At the moment there is no separate switch for it because it is so
    similar to calendars. We can consider adding a separate switch later
    if there is need for it.
    
    Access to the Google Tasks API was turned on in the Google APIs
    console because the documentation suggests that it is the way to go.
    However, some third-party websites [1] mention a scope string that can
    be put in the sources. Given that Google's documentation has proven to
    be unreliable in this regard we had added it too. For some context see:
