Changes

One approach would be to keep a list of the <i>N</i> most recent typed notifications. When a visit comes through, associate that visit with the typed nofitication and remove it from the queue. This will break if the URL is loaded in more than one window, but will work in the common case. We will also have to clean up this list because some typed URIs are invalid and will never be visited, but some will take a long time to load. It is not clear what the lifetime of these should be. We would also like to add a bookmark notification equivalent to the typed flag for when the user follows a bookmark. It would be best if the typed/bookmark flags could be associated with a specific docshell. When the user types something, it would associate a given URL as typed/bookmarked for the docshell. The next visit on that docshell will either be that URL if it was loaded correctly or something else if the user gave up and followed a link instead. If we see there is something else, we can immediately discard the typed URL.
