Support diff editor

Support the diff editor like you've supported the regular editor in MonacoFX and index.html

See the following for an example:

Good point. We will look into this.

And of course you are welcome to contribute if you want :)

Will do if I can make time. I did a quick hack to support the diff editor but it's not ideal.
