Add a Related String Addressed by Name

Demonstrates the Chilkat Email.AddRelatedString2 method, which adds a related item from an in-memory string, addressed by the name used in the HTML rather than by a generated Content-ID. The first argument should match the filename used in an HTML img src or a stylesheet link href; the second is the Unicode content; the third is the charset it is converted to. Related items are images and style sheets embedded to support the HTML display — they are not attachments. This example embeds a CSS style sheet referenced as styles.css.

Background: This is the string-based, Content-Location counterpart to AddRelatedString. Instead of the HTML pointing at a cid: URL, it keeps a natural reference like href="styles.css", and the related part is matched to it by name. That makes it a good fit when you are turning existing web content into email and want the original relative references to keep working without rewriting them.
