Feature description

Given a constraint violation, the error response generated by the ConstraintExceptionHandler always prepends the object and field name to the message. It would be nice to be able to control whether or not that prepending happens, either globally or per message (if that's even possible).

For example, instead of a message such as:

"message": "requestModel.firstName: First name must not be empty"

Just display this:

"message": "First name must not be empty"

I was able to work around this by creating my own class that @Replaces the ConstraintExceptionHandler and removing the code doing the prepending, but I am sure there's more flexible ways to do this, i.e. configuration-based properties.
