[BUGFIX] Wrong name attribute in custom user rendered items

Configuration items/properties that use a user function to
render the accordant values and possibilities (like, e.g.
saltedpasswords does in the Core) have a wrong name attribute.

• fieldName: Extbase prefixed form name
• fieldValue: the value of the field to be shown
• propertyName: Name of the property, e.g. "some.setting"
