edit-pages.php does not correctly order pages by menu_order

[torfason]

In version 2.5, as well as in the most recent checkout, the list of pages generated by edit-pages.php does not correctly order pages by the menu_order column. The reason is the lack of a break statement in query.php, which causes the menu_order case to fall through to the next case and the $orderby variable gets set to $wpdb->posts.ID.

A patch detailing an insertion of this break statement is attached, which seems to fix the problem.

Dupe of #6587 but since this one got the fix, I'll close the other one.
