Adds an orderstep to e-commerce where non-paid orders are followed up. In that email, you can ask the customer to
a. cancel the order b. pay for it
Please install in mysite/_config/ecommerce.yml as follows:
OrderStep:
order_steps_to_include:
# more steps here ...
stepX: OrderStepPaymentCheck
# more steps here ...
X is the step number.
Note that this step replaces the OrderStep_Paid in most cases. After that you will need to run a dev/build?flush and delete any Ordersteps that can be deleted (see: http://mysite.co.nz/admin/shop/OrderStep).
After the flush you may also need to manually remove the 'Paid' step from the Order Step Settings.
In your template OrderStepPaymentCheck_Email, you want to add a $Order.RetrieveLink.
You also want to make sure that customer can cancel and can pay if the order has not been paid yet (see: http://mysite.co.nz/admin/shop/OrderStep).
