        REGRESSION (r61285): AIM 2.1.296: Code rendered as text in Welcome screen
        https://bugs.webkit.org/show_bug.cgi?id=46134

        AIM clients linked against versions of WebKit prior to the introduction
        of the HTML5 parser contain markup incompatible with the new parser.
        Enable parser quirks in this case to remain compatible with these
        clients.

        * WebView/WebView.mm:
        (shouldUsePreHTML5ParserQuirks): Returns true if the embedding
        application is AIM and was linked against a version of WebKit prior to
        the introduction of the HTML5 parser, or if the
        WebKitPreHTML5ParserQuirks WebPreference is enabled.
        (-[WebView _preferencesChangedNotification:]): Call
        WebCore::Settings::setUsePreHTML5ParserQuirks().
