start-dialog-001 does not start

[morisil]

Even though I fixed the code of this module to finally compile (issue #19), it still doesn't start:

Exception in thread "main" kotlin.UninitializedPropertyAccessException: lateinit property application has not been initialized
	at org.openrndr.Program.getApplication(Program.kt:43)
	at org.openrndr.Program$mouse$2.invoke(Program.kt:208)

	at java.base/java.lang.reflect.Method.invoke(Method.java:567)
	at com.intellij.rt.execution.application.AppMainV2.main(AppMainV2.java:131)

It's hard for me to tell the original intention behind this code.
