Some tweaks to the Open ID authentication support (which I've been using very happily, BTW). It now respects the "Keep me logged in" checkbox on the login page. It also cookies your openid url for less typing on future visits to the login page.

Also, we try to avoid calling store_location on expiry if the triggering url was an ajax request (like one of the periodically executing javascripts). Storing the location doesn't make sense in that case.
