Import of order states from Magento 1.4 and earlier

[andyskipper]

The connector presently makes a call to retrieve all order states using this call in Openlabs_OpenERPConnector_Model_Sales_Order_Api:

    /* Retrieve order states */
    public function getOrderStates() {
        return Mage::getSingleton("sales/order_config")->getStates();
    }

The getStates() method was private until Magento 1.5, and will fail for any versions prior to that. In 1.4 and earlier, two separate methods exist instead, the results of which could be combined to achieve the same result, for example:

/* Retrieve order states - new version */
public function getOrderStates() {
    $states = array();
    try {        
        $states = Mage::getSingleton("sales/order_config")->getStates();
    }
    catch (Exception $e) {
        /* getStates() not found - early Magento version */
        $visibleStates = Mage::getSingleton("sales/order_config")->getVisibleOnFrontStates();
        $invisibleStates = Mage::getSingleton("sales/order_config")->getInvisibleOnFrontStates();

        $states = $visibleStates + $invisibleStates;
    }
    return $states;
}

Its awesome Andy, I'm bit busy right now and check this out later and make this available in code ASAP.
