New feature additions

1. Added support to apply a discount on checks automatically if paid with cash (Cash Discount) 
   
   This allows a merchant to provide an incentive to his customers when they use cash payments instead of credit cards. 
   
   
   
   

   This option is only available when the system is configured to use the PayFacto USA payment protocol in the “Electronic funds transfer” module
   
   
   
   
   To configure a discount to be used as the cash discount you need to select the option “Cash Discount” located in the misc section of the discount configuration page.
   
   
   
   
   You also need to provide the discount rate to be applied.
   
   
   
   Once the discount is configured you need to associate that discount to the “Cash” tender type 
   
   
   
    
   On the options page of the tender type configuration select the option “Eligible for cash discount”
   The system will print on the check both the full and discounted total to inform the customer of the amount to pay when using a credit card or cash.
   The label printed on the check can be customized from the “Setup /Utilities” module.
   Navigate to “Configuration \ System configuration \Payments ”. Change the value for the field “Cash total”. By default, this value is set to “Cash total”.
   
   
   
   
   
   
   When a cash discount is configured. The POS will display both totals to the operator
   
   
   
   
   When using the cash tender the discounted value will be used.
   
   
   
    
   The cash discount will be displayed on both the employee reading and back-office report in the discount section
