Instead of storing all storage objects in static memory, we now follow the the spec by lazily creating a unique Storage object on each document object. Each Storage object now holds a 'proxy' to the underlying backing storage. For now, this proxy is simply a reference to the backing object. In the future, it will need to be some type of interface object that stores on a SQLite database or similar. Session storage is now correctly stored / tracked as part of the TraversableNavigable object. Local storage is still stored in a static map, but eventually this should be factored into something that is stored at the user agent level.
