Could you please extend the examples to also make auto-completion, e.g. in `hello-kotlinx-html.scriptwithdeps.kts`, work in IntelliJ? For example, if I'm extending `ScriptWithMavenDeps` with a dummy property like ``` abstract class ScriptWithMavenDeps { val dummy: String = "oink" } ``` what does it take to offer `dummy` when typing `this.` in `hello-kotlinx-html.scriptwithdeps.kts`?
