    window: Move Player to Application
    
    Architecturally-wise, the music player object is not
    tied to the active window in any form. So holding it
    in Window is an anti-pattern - Window is not the right
    place for Player to be.
    
    Move Player to Application, and make it a property so
    that it can be accessed as application.props.player.
    It is a readable property, since there is no reason
    to change it.
    
    At last, add docstrings to the init method.
