Improved error visualization during development
Fix in reloading hibernate due to bug in grails

See https://jira.grails.org/browse/GRAILS-8805 for details
Added field tag to the FormTagLib
Improved equals and hashcode methods for Data and FieldSubType
Enabled externalized log4j configuration
Added spring-generated files
Added possibility to enter data for each questionnaire and see the results.

The default way is very basic, and can be overridden by overriding a
view (form or results)  in the questionnaire/{questionnaireKey} directory.
If you need more fine-grained control, you could also create a new
QuestionnaireController in a namespace called {questionnaireKey}. By placing
methods called 'view', 'submit' or 'results' in there, you could override
the default behavior.
