[development] Menu update -- the older your database is, the better

[Karoly Negyesi]

Hi,

http://drupal.org/node/147657 is now RTBC and I really countercheck
every presumption about the menu table and have erected various
safeguards against weird, weird menu tables -- please test! If you
have a database which you upgrade since 4.5 for example... that'd be
valuable.

Thanks,

NK
