Serialize MIME to a StringBuilder

Demonstrates the Chilkat Mime.GetMimeSb method, which serializes the complete MIME entity and appends it to a StringBuilder. The only argument is the StringBuilder; existing content is preserved.

Background: Serializing into a StringBuilder avoids creating a new string and is convenient when you are accumulating output or building a larger document. Because it appends, you can assemble several pieces in one buffer. As with GetMime, use the BinData form for content with arbitrary binary bytes.
