Allow 'propertyName' without specific 'class' or 'superclass' as override template.

[aadrian]

Please allow to override propertyName without a class or superclass.

For the moment only:
grails-app/views/_fields/class/propertyName/
or
grails-app/views/_fields/superclass/propertyName/
are supported.

But in quite a few cases, the same name, e.g. "description" , or "notes" needs the same rendering across all domain classes (e.g. a text area or an editor field for the mentioned case).

Thank you.
