Title: orderBy() should accept uppercase order direction

`query->orderBy()` should accept an uppercase parameter for the direction because it is the SQL convention and because it is the initial behavior in Laravel.

```PHP
// Illuminate\Database\Query\Builder
public function orderBy($column, $direction = 'asc')
{
$direction = strtolower($direction) == 'asc' ? 'asc' : 'desc';

$this->orders[] = compact('column', 'direction');

return $this;
}
