Setters return this about lombok

It would be useful for make chained invocation if the setters generated by
Lambok return the instance of the object.

Ej.

class Factory {
Factory setSomething(Something something) { ... return this; }
Factory setOther(Other other) { ... return this; }
Thing result() { ... }
}

Thing thing = new Factory()
.setSomething(something)
.setOther(other)
.result();

That would be the builder pattern. As unfortunate as it is, the understanding of a 'setter' in the greater java
community is a method that returns void.

We will add the Builder pattern at some point, though. That will help with chaining needs.

Adding a 'returnThis=true' kind of parameter to @ Setter also seems a bit unfortunate, as we'd have to
duplicate it to @ Data lest people are forced to add a tonne of @ Setter annotations. And yet, that feels like a
path that leads to 50 options on @ Data which is something we're trying to avoid - Hence, builder pattern.

I did make an issue for adding a Builder for you, though :)
