Add fu->redirect, change $st->row behavior on 0 results, minor fixes

Browse source 
And with this, I have a working rewrite of the manned.org backend into
FU. \o/

The $st->row methods are very useful even for queries that may not
return anything, so their old behavior was unhelpful. Interestingly
enough, the error-on-multiple-rows did catch an actual bug in
Manned.org, so I'm keeping that behavior.
