DATACMNS-1021 - Add Order.asc(…) and Order.desc(…) factory methods.

We now support Order creation with Order.asc(String) and Order.desc(String) factory methods as shortcut to constructor creation via new Order(Direction, String).

Sort.by(Order.asc("age"), Order.desc("name"));

Deprecated Order(String) constructor in favor of the Order.by(String) factory method. Replace references to new Order(String) with Order.by(String).

Original pull request: #211.
