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

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.

Start by tracing template resolution for grails-app/views/_fields/class/propertyName/ and grails-app/views/_fields/superclass/propertyName/. Determine where a propertyName-only override could fit in the lookup order, then verify that one shared template is used for fields with the same name across different domain classes. Done means propertyName-only overrides work without requiring a class or superclass.
