Moultingyaml does not conserve the order for maps and case classes

[apps4uco]

Although the yaml specification does not require conserving the order, snakeyaml does conserve the order.
This makes it easier to round trip yaml to yaml or yaml to case class and back.

Attached: Modifications to conserve the order for maps and for case classes.

Disclaimer, please test the code, it compiles and passes a quick test.
It would be great if you could include this functionality in the next release.
