* We split the "update available" off to a top-level menu item, instead
of a sub-item under Help. This gives explicit text saying an update is
available.
* Change the icon from an hourglass to a slightly more 'updatey' image.
* We now re-cehck every week even if an update is marked available. That
way people who delay for longer than it takes to release a new version
will get the latest when they do update. It also gives them a reminder
every week so that hopefully those delayers will be less common!
