application.ini doesn't get replacements such as ${{app_name}}

Unlike specified in these pages,

https://github.com/sbt/sbt-native-packager/blob/master/src/sphinx/topics/play.rst
application.ini doesn't get anything replaced (with and without play)
To try just create a basic project with what is suggested in https://github.com/sbt/sbt-native-packager/blob/master/src/sphinx/topics/play.rst

Hi @knshiro . Yeah, that's true and a miss documentation. We will remove this from the docs and see if we should add this. We recommend using the build.sbt approach, e.g.

javaOptions in Universal ++= Seq {
 "-Dhttp.port=8080",
 "-Dapp.user=user",
 s"-D.app.version=${version.value}"
}

This approach is a lot more flexible as you no longer depend on magic string-replacements, but use your variables directly as they are.
