Set a MIME Body, Preserving Content Headers

Demonstrates the Chilkat Mime.SetBody method, which sets the current part's body while preserving the existing content headers (Content-Type, charset, Content-Transfer-Encoding). The only argument is the body text; it is a void method.

Background: Unlike the SetBodyFrom... methods, which set both the content and the headers that describe it, SetBody replaces only the body text and leaves the existing Content-Type and encoding in place. That is what you want when the media type is already correct and you simply need to swap in new content — updating a templated part, for instance — without re-declaring its type.
