Adding docs about null parameters

[Turini]

related with #532 and #660

The default should "null when not present" if I remember. Or not?

[garcia-jj]

Looking the code, the default behavior is null when no parameter was found. https://github.com/caelum/vraptor4/pull/660/files#diff-ac6ae891d48b200fe6c56de7d8dc126bR98

ops.. I've changed the method condition but forgot to push 8a1ba5a The default
behavior of VRaptor 4 is always instantiate method parameters, I didn't change it.

Ok. 🔫

Hi, do you know when this feature will be released? I'm working on JBoss
Forge plugin for VRaptor 4 to agilize (scaffold) development in my
organization (Supremo Tribunal Federal), and the generated @manytoone
attributes throws org.hibernate.TransientPropertyValueException because it
contains an parent Entity with null identifier.
