FEATURE: Order Approval Settings

New Order Approval Settings

- New Store Setting "Approval Required for Orders Over"

- New Order Status Settings "Approval Required Status" & "Approval Granted Status"

- New Product Flag "Force Separate Order" will cause a cart validation error with message and disallow checkout if the item is in cart with any other items

- New Product Flag "Approval Required" 

If an order is placed with any items requiring approval or if the order total is over the new store setting, its status will be set to the status selected in the "Approval Required Order Status" setting. If the order needs to be approved, the customer will receive the "Approval Required Order Status" email template set on the order status screen. 

Also, when this order is placed, the email template for the "Approval Required" status is sent to all of the customer's parent customers, i.e. managers. This email will contain two links (not actually present in the email template) - one to APPROVE and the other to DENY the order. If the order is approved, its status will be set to the status selected in the "Approval Granted Order Status" setting. If the approval is denied, the order will be set to canceled.
