Duilib中Webbrowser事件完善使其支持判断页面加载完毕

在多iframe的页面中，需要结合DISPID_DOCUMENTCOMPLETE和DISPID_NAVIGATECOMPLETE2两个事件判断页面是否加载完毕，而duilib中没有提供对DISPID_DOCUMENTCOMPLETE的支持。

要支持DISPID_DOCUMENTCOMPLETE，需要修改UIWebBrowser.cpp、UIWebBrowser.h和WebBrowserEventHandler.h三个文件

1.WebBrowserEventHandler.h文件

添加virtual void DocumentComplete()；
