#50 Unable to map to SortedSet

[Peter Monks]

If the target of a collection mapping is a
java.util.SortedSet Dozer fails with the following
exception:

Dozer should support SortedSets since they're used
quite frequently in Hibernate POJOs.

The attached JUnit test case demonstrates this behaviour.
