Extracted a Projections value object in the Cargo aggregate, which handles predictions about the future of the cargo (next expected activity, ETA).

Migrating to a much cleaner way to propagate handling updates to the cargo aggregate: Cargo.handled(HandlingActivity).

Moved some logic into *Status enums, making them richer.

Improvements to a number of toString()s
