WebViewNotifier class

State notifier that controlls all state for a web view.

Webview implementations must call setController as well as the various notify* calls to update its underlying WebViewState.

In return, this notifier can be used by other widgets to display the webview's title and other data without tight coupling or async issues.

This notifier also holds a pullToRefreshController that can be used by the webview to control its own pull to refresh indicator. This class updates the state of the pull to refresh controller accordingly.
