fetchPairs improvement

[bystac]

can you add ->fetchKey('some_key') it's will be similar to fetchPairs but embed all row
function fetchKey($key) {
$return = array();
foreach ($this as $row) {
$return[$row[$key]] = $row;
}
return $return;
}

Now I can overcome the missing joins functionality
$leads = $nORM->leads()->where($criteria)->order('leads.id DESC');
$leads_data = $nORM->leads_data()->where('lead_id', $leads)->fetchKey('lead_id');

Allow returning whole row from fetchPairs, closed by 5c006aa
