Order of properties

[joachimschaaf]

Problem:
The properties are not written to the file in the order that is defined in the pom.xml

It would be helpful if the order would be preserved.

The challenge in maintaining any type of ordering is that java.util.Properties is implemented with a Hashtable which is inherently unordered. By using the built-in Properties class, it means that escaping of values and ensuring the validity of the file happens automatically.

But feel free to suggest alternative implementations (or better yet, submit a PR) and we can see if that works.
