[epiphany/downloads: 5/5] ephy-window: add new downloads UI

[Diego Escalante Urrelo <diegoe src gnome org>]

commit 10ab28531735657e8956d2950d73a95529f969c5
Author: Diego Escalante Urrelo <descalante igalia com>

    ephy-window: add new downloads UI
    
    Downloads are shown per-window, imitating Chromium's bottom bar.
    If the window being closed has active downloads, a warning dialog will be shown
    just as when forms have been modified but not sent.
    An active download is any download that is not yet 100% complete.
    
    Bug #618443
