A couple of requests to add functionality to the "Manage Orders" screen:
1. Add a search by billing/shipping last name (we are more likely to know customer's last name than their email address)
2. Add the ability to send an email to multiple order simultaneously. I.e., from Manage Orders screen, select desired orders, then access Order Emails link and select email template to be used and send emails (must display Order Emails link on Manage Orders screen).
