[epiphany/downloads: 8/13] ephy-window: add new downloads UI

[Diego Escalante Urrelo <diegoe src gnome org>]

commit 1d57e69a9ceddc13d9de84da82a89082a92c8d16

    ephy-window: add new downloads UI
    
    Downloads are now shown per-window, imitating Chromium's bottom bar.
    If a window with ongoing downloads is closed, their downloads will go to
    another window. TBD: it might prove better to just ask if you want to cancel
    them or not.
