Using Play!'s built in Form validation

Only way to use Form<CLASS> is to have the form fields be public members.  To minimize the impact on the original code style I made an assemblies package where you would put classes for form validation.  I didn't use the built in annotations from EBean because they gave fairly crappy error messages (error.required or error.invalid).  I rewrote the form helpers to be a bit more clear while maintaining their functionality.
