I think that if sub latestbuilds simply accepts a nixname we are set!=20

Add the Perl lines=20

   my $nixname =3D $c->request->params->{nixname};
   $filter->{nixname} =3D $nixname if ! $nixname eq "";

So we can do
"http://hydra.gnu.org/api/buildToHash?nixname=3Druby-2.2.3", assuming
the DB rec has a field named nixname - which I think it has, because
the result already has the column.
