Handle NSCoder / Saved Bundle States

[breautek]

Android has a concept of saved bundle states. Natively it allows an opportunity to save view state so that it can be reconstructed later when the app pauses -- and potentially destroyed. This typically can happen when using intents or other app delegation tasks, such as when using the camera.

iOS equivilant I believe is the NSCoder system.

This process is a synchronous process, which makes storing webview JS state tricky.
