    app: Factor out 'start-client' action
    
    The telepathy client is currently started if necessary when the
    application is activated. However as there are cases for running
    the client without activating the application (read: creating a
    window), it makes sense to split out the code. While for now a
    separate function would do just fine, we'll eventually want the
    functionality available even when Polari is not running, so add
    a corresponding action.
