Actually Move is pretty messed up without Javascript.

1. You click Move (that calls the url mode=manage&action=move_up&rule_id=XX&hash=XX
2. The rule moves, and the page that follows winds up being the front page (language selector if you have langs installed). But the current URL is still mode=manage&action=move_up&rule_id=XX&hash=XX
3. Click the submit button on the lang selector to re-enter the rules, but because of the stale move params, another move gets called, so the rule ends up moving again upon clicking the lang selector submit button.
