Add Customer Email to admin notification

Hi,

For the customer email address, you can add such tag in the HTML version of the email via the menu System>Emails if you have the Business edition:
{VAR:customer.user_email}
For the "Hi", on that same screen, in the "preload" section, you add the line below at the beginning:
<?php $mail->to_name = "xxx"; ?>
where xxx is the name you want to display in the email after the "Hi"
