Item1172: Foswiki::Request::param fails if parameter name is 0 or ''

The following code:

    my $req = new Foswiki::Request("");
    $req->param(-name => 0,  -value => 'abc123');
    $req->param(-name => '', -value => '');

    print scalar $req->param,"\n";

should print 2, but currently prints 0. It's unlikely to happen in practice a parameter named as 0 or as '', but Foswiki::Request::param must behave well in both situations.
