- fixed <rdar://problem/5092556> Default UA spoofing is always off until explicitly toggled

        * WebView/WebView.mm:
        (-[WebView _commonInitializationWithFrameName:groupName:]):
        initialize the cached value of _private->useSiteSpecificSpoofing here; formerly it would not
        be initialized correctly in the common case of WebViews that use [WebPreferences standardPreferences]
