Implement shouldOverrideUrlLoading to open hyperlink on HTMLViewer.

Since WebViewClient was set to WebView, hyperlink has not been working
on HTMLViewer because WebViewClient has empty shouldOverrideUrlLoading.
Therefore, copied shouldOverrideUrlLoading from WebViewContentsClientAdapter.java in Android WebView
Opensource.
