Process a potential change in navigation state. This compares the current URL to the last URL seen by this method.
If there is a different, it will replace the content area with the new desired page.,
Note that unlike the old hash-based method, there is no catch-all listener for hash changes. Rather, anything
wishing to change the hash should use goPath to have the navigation automatically performed (if the
entire desired state can be determined from the path alone), or setPath if you wish to set the location
but manually replace the page contents.
