When creating a new field, updating toString should be optional

Today, when we create a new field to a Java class (or CDI bean...), the field is automatically added to the toString method. It would be good to have the option not to update it, by adding a --updateToString boolean parameter.

The following command create a class, adds two fields, one updating the toString, the other no :

java-new-class --named MyClass
java-new-field --named defaultUpdatesToString
java-new-field --named doesNotUpdateToString --updateToString false
