Add default delete behavior error messages (and the option to configure these defaults for the project)

The delete behavior messages can be configured on in the domain model, but usually follow the same pattern.

Something like: " Can't delete {object A} because it has an association with {object B}, please remove this association first.  "

It would a nice productivity gain if we can configure a default message (with parameters) for this behavior, instead of typing / pasting and editing it for every association. And of course for each language  =)
