Add CKEditor/WYSIWYG to the Event Confirmation Email Text Field
Per a discussion with Eileen, it would be great to finally get the Confirmation Email Text field of Event Online Registrations to use CKEditor. That will allow admins to create much nicer confirmation emails (with embedded graphics and branding) without the need to learn HTML. Given the Registration Screen Introductory Text and Thank-you Screen text both have this option, it seems like a good idea to also have it for the confirmation email.
