[Ideas] Expose entity attribute name and label (and plural) in expressions

Getting rid of "[Entity].[Attribute]" and replacing it by:

• Entity.Attribute.Name
• Entity.Attribute.Label
• Entity.Attribute.LabelPlural

This would be a small change that could eventually provide robustness in the TrueChange mechanism for (for instance) replacing entities in aggregates affecting tables and forms, and eventually even table headers and form labels.

Would affect table sorting mechanism, but impact would be reduced for custom scenarios like sort priority, because it would still be resolved to the same string in runtime. Legacy could would not have to be changed.
