    sidebar: Drop use of AppWindow singleton
    
    Instead of using the AppWindow singleton, Sidebar now has its own
    reference to AppWindow that it receives through a parameter to setup_ui().
    
    This is needed to drop the use of AppWindow singleton and therefore to
    make multiple windows possible.
