GValidation Plugin Version 0.4.

GValidation plugin 0.4 is out now.

In this release, manually enhancing regular Groovy class in Griffon applications is replaced by an @Validatable annotation, which means that any class annotated with @Validatable should be automatically synthesised with validation capability. The dynamic errors field in models and Validatable objects are now Bindable, and there is a pre-validation callback.
