querydsl-codegen: add an option to generate chained setters

[amanteaux]

It would be great to be able to generate chained setters in the generated beans. This way we could write something like:

MyGeneratedBean bean = new MyGeneratedBean().setProperty1("value").setProperty2("value");

If you are ok with the idea, I could do the change in the BeanSerializer class to add the option to generate chained setters.
