## Table aliases

ORM will now alias the main table in a query to the model's singular object name.
i.e. Prior to 3.2 ORM set the from table like so:

    $this->_db_builder->from($this->_table_name);

As of 3.2 it is now aliased like so:

    $this->_db_builder->from([$this->_table_name, $this->_object_name]);

If you have a model `Model_Order` then when building a query use the alias like so:

    $model->where('order.id', '=', $id);
