Download POP3 Email using UIDLs

Demonstrates how to download POP3 email by first getting the complete set of UIDLs and then downloading email by calling FetchEmail for each UIDL. This is equivalent to calling CopyMail, except your application can process each email as it arrives instead of waiting for the entire bundle to be downloaded. Also, it's better protection against potential out-of-memory issues if your mailbox has a very large number of messages. There is no performance difference between fetching emails individually vs. calling CopyMail.
