Pinch to zoom no longer works which seems to be due to SDL finger IDs changing. There is a new pinch event specifically for this which should be used instead.
When the WebView opens a URL that is neither a principia: link nor a
community-host page, it hands it to an external app with
startActivity(ACTION_VIEW). On a device with no app able to open the URI
that call throws ActivityNotFoundException and the activity crashes.
Wrap the launch in a try/catch so an unresolvable link is logged and the
WebView dialog still closes cleanly.
The community site has links to all sorts of external websites that really does not like the webview, and the user likely wants them to be opened in an external browser in this case rather than be confined to the app's webview.
