[connections/wip/fullscreen] window, display-view: Handle F11 to fullscreen

[Felipe Borges <felipeborges src gnome org>]

    window, display-view: Handle F11 to fullscreen
    
    This allows for running the app in fullscreen. We still need to
    add a menu entry for this and sort the topbar behavior (allowing
    mouse drag to escape fullscreen mode, like Boxes).
    
    Fixes #5
