[evolution/gnome-3-0] Bug 653247 - Don't show TIFF documents inline

    Bug 653247 - Don't show TIFF documents inline
    
    image/tiff is omitted because it's a multi-page image format, but
    gdk-pixbuf unconditionally renders the first page only, and doesn't
    even indicate through meta-data whether multiple pages are present
    (see bug 335959).  Therefore, make no attempt to render TIFF images
    inline and defer to an application that can handle multi-page TIFF
    files properly like Evince or Gimp.  Once the referenced bug is
    fixed we can reevaluate this policy.
    
    (cherry picked from commit 162266bb99581ba2ddb171995d352e5dabcbd9ca)
