Users cannot be logged in automatically

For some websites it is convenient to be able to log in the user upon succesful payment. This is standard functionality in Ubercart. However, the module does not support this.

This can easily be fixed by changing line 321 in uc_quickpay.module from
$output .= uc_cart_complete_sale($order, true);
to
$output .= uc_cart_complete_sale($order, value_get('uc_new_customer_login',false));
