EMFormatHTML now holds a sealed EWebView instead of a public GtkHTML, accessible through em_format_html_get_web_view(). Rename e_mail_reader_get_html_display() to e_mail_reader_get_formatter() and have it return an EMFormatHTML instead of an EMFormatHTMLDisplay, since that's usually the type you want (or else an EMFormat, but never an EMFormatHTMLDisplay).
