Add webserver for Bezier Curve Editor

[nefarius]

Communicating with the JavaScript based BezierCurveEditor can be simplified by delivering it with an integrated web server like EmbedIO.

As the server host is now built on ASP.NET Core, the editor files can be served from there and should be moved to the appropriate location, maybe even converted into a Razor page or similar.

Some resources where the original editor came from or can be replicated with:

• Bezier curve
• Cubic Bezier Curve editor made with React & SVG
