Title: Changing from the `browserTag` to `webview`.

Looking at the latest documentation for the chrome packaged apps it has a webview permission, nothing about a browser tag.

See http://developer.chrome.com/apps/app_external.html

Also, from the example browser app it does not look to need the experimental flag: https://github.com/GoogleChrome/chrome-app-samples/blob/master/browser/manifest.json
