Added some exception handling around localStorage.setItem(), and optionally pass the exception to a cacheError() callback if defined. My use case is to catch any QUOTA_EXCEEDED_ERR exceptions, and to use the callback to selectively clean up some cached items in that event. I couldn't find a better way to check for over limit errors, I'm not sure if this is the best approach or not.
