Output the dependencies in a consistent and natural order

As of 2.0-alpha-5-SNAPSHOT 31-AUG-2007 the dependencies when output are in random order as I suspect they come straight form a Set.

This makes it really difficult for a human to parse the dependencies.
Ordering them using the natural artifact order before output would be a great improvement.

In particular dependency:tree is very hard to read when they are not ordered.
But if each level were ordered using the natural artifact ordering it would be much easier to read and to work out where the dep problems lay.
