*Title: Order confirmation handler.

*Incentive:
Be able to control the handling of confirmation email that are sent to
the administrator and customer when any product is confirmed in the shop.

*Documentation:

Modifications are done in ezshopoperationcollection.php where you have
the function sendOrderEmails()

Instead of sending the email directly in this function, it's made a eZConfirmOrderHandler 
which can be customised in a extension.

The handler need to implement a execute function which should receive a parameter.

The parameter should be an array and will contain:

array( 'email' => 'thecustomeremail@ez.no',
       'order' => $order );

- thecustomeremail@ez.no: A valid email address that is entered by the customer.
- $order: The current eZOrder object.

The confirmorder handler should be placed in:
kernel/classes/confirmorderhandlers/ and should have the prefix confirmorderhandler.php

The default handler is:
kernel/classes/confirmorderhandlers/ezdefaultconfirmorderhandler.php

example of a custom handler:
extension/myextension/confirmorderhandlers/mycustomconfirmorderhandler.php

You do also need to add a setting in shopaccount.ini:

[HandlerSettings]
# A list of directories to search for shopaccount handlers
Repositories[]=kernel/classes
# A list of extensions which have shop account handlers
# It's common to create a settings/shopaccount.ini.append file
# in your extension and add the extension name to automatically
# get handlers from the extension when it's turned on.

# Settings for how order emails should be handled in the shop/checkout
# default is to send confirmation emails to both customer and admin.
[ConfirmOrderSettings]
Handler=ezdefault
# Allows for overriding a handler with another
