Append MIME from a StringBuilder with Flags

Demonstrates the Chilkat Imap.AppendMimeWithFlagsSb method, which uploads MIME contained in a StringBuilder and sets its initial system flags. The first argument is the mailbox, the second is the StringBuilder, and the third through sixth set \Seen, \Flagged, \Answered, and \Draft. This example uploads to Drafts with the draft flag set.

Background: This is the StringBuilder form of AppendMimeWithFlags. Passing the MIME as a StringBuilder avoids copying a large message into an intermediate string and is convenient when you already built or loaded the message into a StringBuilder (for example with LoadFile).
