[nautilus/wip/csoriano/destktop-split2: 30/54] window: allow to create custom slots in subclasses



commit 713d32b204a537f21c75e85162071cc7cb2bd7d9

    window: allow to create custom slots in subclasses
    
    We are not able to create subclasses of window slots, like the one
    we will need for desktop.
    
    So create a vfunc to handle that, and expose the common code in a public
    function so subclasses can use it.
