Support Process Death in WebAuthProvider

[ahibrahimleague]

Changes

This PR fixes issue #779, where Auth0 fails to invoke the registered callbacks due to losing the callbacks that were registered when calling await() or start().

This was achieved by serializing the Auth0Manager state into JSON and saving this JSON into the AuthorizationActivity bundle. When restoration happens, we rebuild the Auth0Manager again from the already saved bundle.

In order though to receive the callbacks from the newly restored OAuthManager, we need to listen to the callbacks through an application-scoped callback, so I've added a couple of new APIs called addCallback and removeCallback (open for naming and redesign changes) that clients if interested, they can call add/removeCallback from onStart and onStop, so that when the oauth authentication request's result returns, would get invoked with the captured credentials.

• Added addCallback and removeCallback to WebAuthProvider.
• Updated the sample app with the new API.
