    epubview: Fix epub books always opening on page 1
    
    The page/chapter read count is not honored for epubs and the ebook is
    reopened on the first page instead.
    
    The epub view's slider's range is set to be between 1.0 and X where X is
    the number of pages in the document, after the document has been loaded,
    but that range is between 0.0 and 1.0 by default.
    
    After the epub has been loaded, the navigation bar is created, and the
    "value-changed" signal that will save the current page connected.
    
    As the epub document is "set" for the bar, the range is first changed to
    match the number of pages in the document, changing the range, thus
    changing the "current page", overwriting the saved page, then the page
    is restored.
    
    (Note that the on-disk page number is 0-indexed, as is the "chapter"
    libgepub property)
    
    Closes: #11
