    EWebView/EMailDisplay: Setup custom CSS styles to DOM right after document loads
    
    The custom styles, those which are added on-the-fly directly to DOM, were
    added only after whole document was completely loaded, which included also
    sub-frames content, thus when these were slow to download for any reason,
    the main frame content, like the top header bar, was shown with a default
    style, which is white background and black text color. The WebKitWebView's
    document-load-finished signal is emitted whenever the actual HTML content
    is loaded, and the DOM is available as well, for each frame, including
    the main frame of the WebView, thus updating/setting custom CSS styles
    in this signal handler makes the loaded frames look as expected, without
    waiting for other frames in the document to finish their load.
