修复进入帖子自动打开 Youtube 网页的问题 #28

帖子中有 Youtube 视频时，会触发 webView(webView: WKWebView,
decidePolicyForNavigationAction navigationAction: WKNavigationAction,
decisionHandler: (WKNavigationActionPolicy) -> ()) 方法。

po navigationAction 返回 <WKNavigationAction: 0x7fd0f9422eb0;
navigationType = -1; syntheticClickType = 0; request =
<NSMutableURLRequest: 0x61800001e700> { URL:
https://www.youtube.com/embed/xMFs9DTympQ }; sourceFrame = (null);
targetFrame = <WKFrameInfo: 0x7fd0f9401030; isMainFrame = NO; request =
(null)>>

所有这里判断一下 navigationType 值来修复进入帖子自动打开 Youtube 网页的问题
