[dw-free] Revamp /update

[fu]

[commit: http://hg.dwscoalition.org/dw-free/rev/b04f39db8113]

http://bugs.dwscoalition.org/show_bug.cgi?id=2524

Don't blow away existing ordering if we didn't post anything (e.g., when JS
is off, we get redirected to a page where you can tweak visibility, but not
order)
