    Decode last component of URIs to determine file names for saving
    
    In the logic to determine which filename to use when saving a non-HTML
    resource the last component of the URI was being used as-is, which could
    include percent-encoded characters. Calling soup_uri_decode() before
    using the value ensures that we present readable file names to the user.
    
    Also, this stops using g_file_get_basename() to extract the last
    component of an URI because it would horribly break on platforms which
    do not use a slash (“/”) as path separator.
    
    This fixes bug #780086
