Magento 1.9: Overwrite Core Account Controller for Custom Login Actions

I have been trying without success to overwrite a couple of functions in the Account Controller within the customer folder of Magento core (originally I had just modified the core files, but soon realised that isn't the correct way).

To get to where I am currently I have:

1. Created a folder structure in app/code/local:
   My folder structure is:

   - Speedcrete (module name)
       - Customer (core magento module to overwrite)
           - controllers (contains accountcontroller.php)
           - etc (which contains the modules config.xml)
   

2. Created an XML file called Speedcrete_All.xml in app/etc/modules

   The files look like:
   Account controller:

   <?php
   /**
    * Customer account controller
    *
    * @category   Speedcrete
    * @package    Speedcrete_Customer
    * @author     Speedcrete 
    */
   require_once 'Mage/Customer/controllers/AccountController.php';
   //we need to add this one since Magento wont recognize it automatically
   
   class Speedcrete_Customer_AccountController extends Mage_Customer_AccountController 
   {
       public function indexAction()
       {
           echo "jlkgfjdlfjgf";
           die();
           parent::indexAction();
       }
   
       /**
        * Customer login form page
        */
       public function loginAction()
       {
           echo "hello world i am being overwritten";
           die();
           // if we've got come from the checkout page, send variable to front end to be displayed as message
           if (isset($_GET['checkout_page'])) {
               $origin_page = $_GET['checkout_page'];
               $coupon_code = $_GET['coupon_code'];
   
               Mage::register('message' , 'You need to be logged in before you can use coupons!');
               Mage::register('checkout_flag', '1');
               Mage::register('coupon_code', $coupon_code);
   
           }
           if ($this->_getSession()->isLoggedIn()) {
               $this->_redirect('*/*/');
               return;
           }
           $this->getResponse()->setHeader('Login-Required', 'true');
           $this->loadLayout();
           $this->_initLayoutMessages('customer/session');
           $this->_initLayoutMessages('catalog/session');
           $this->renderLayout();
       }
   
       /**
        * Login post action
        */
       public function loginPostAction()
       {
           echo "hkjhfkjhdskfhkjdfsh";
           die();
           if (!$this->_validateFormKey()) {
               $this->_redirect('*/*/');
               return;
           }
   
           if ($this->_getSession()->isLoggedIn()) {

                           if ($referer) {
                               // Rebuild referer URL to handle the case when SID was changed

                   }
                   if ($session->isLoggedIn()) {
                       $session->setBeforeAuthUrl($session->getAfterAuthUrl(true));
                   }
               }
               $this->_redirectUrl($session->getBeforeAuthUrl(true));
           } else {
   
               $this->_redirect('checkout/cart', array('_query' => 'checkout_page=1&coupon_code='.$coupon_code));
           }
       }
   
   
   }
   

3. config.xml within module folder

   <?xml version="1.0"?>
   <config>
       <modules>
           <Speedcrete_Customer>
               <version>1.0</version>
           </Speedcrete_Customer>
       </modules>
   
       <frontend>
           <routers>
               <customer>
                   <args>
                       <modules>
                           <Speedcrete_Customer_controllers_Account before="Mage_Customer">Speedcrete_Customer_controllers_Account</Speedcrete_Customer_controllers_Account>
                       </modules>
                   </args>
               </customer>
           </routers>
       </frontend>
       <layout>
           <updates>
               <mage_customer>
                   <file>speedcrete.xml</file>
               </mage_customer>
           </updates>
       </layout>
   </config>
   

4. then finally the Speedcrete_All.xml which is within app/etc/modules

   <config>
       <modules>
           <Speedcrete_Customer>
               <active>true</active>
               <codePool>local</codePool>
               <depends>
                   <Mage_Customer />
               </depends>
           </Speedcrete_Customer>
       </modules>
   </config>
   

Hopefully this makes sense, nothing happens when refreshing the account login page either when logging in!
