add support for properties with SortedSet and other collection datatype

[paulovitor]

When execute fixture, following exception is displayed:

target = {java.lang.ClassCastException@1827}"java.lang.ClassCastException: Cannot cast java.util.HashSet to java.util.SortedSet"

public class Father {
    private SortedSet<Son> children = new TreeSet<>();
}

Fixture.of(Father.class).addTemplate("valid", new Rule() {
            {
                add("children", has(1).of(Son.class, "valid"));
            }
        });

Is it can add support for other collection beyond Set?

protected TransformerChain buildTransformerChain(Transformer transformer) {
        TransformerChain transformerChain = new TransformerChain(transformer);

        transformerChain.add(new CalendarTransformer());
        transformerChain.add(new SetTransformer());
        transformerChain.add(new PrimitiveTransformer());
        transformerChain.add(new WrapperTransformer());

        return transformerChain;
    }

Or get implementation class from Set interface, instead of create HashSet:

public <T> T transform(Object value, Class<T> type) {
        return type.cast(new HashSet((Collection) value));
    }

@paulovitor I fixed it here f1d4dab.
Any instance of Set should transformable. Let's wait code review and merge.

Ok Mauricio, thanks! ;)
