Use URL rewriting for user account update page

The "UpdateAccount" page displays information as to whether an account
update was successful. All POST account info goes to this page, so use
it with sane URLs.

Before:
AUR_URL/account/?Action=UpdateAccount&U=userfoo

After:
AUR_URL/account/userfoo/update
