Feature Request: Enrinch notification message with additional context

[rootslinux]

Discord notifications support a wealth of enriched content. As of release 1.0.0, we are using color, description, and footer. But as the link below shows, there's much more that could be added with these messages:

Suggestions to consider:

• Add the forum user name and their forum avatar into the author field
• Add the forum name and avatar to the username and avatar_url (will override the default Discord bot name and icon)
