> evaluatedChainedIndex only applies to MessagesDialogExceptionHandler, but it should also be useable on the delegating exception handler.
> evaluatedChainedIndex is to clumsy in most circumstances as it's the type of the exceptions, instead of the level that decide if it should be evaluated.
> ExceptionChainPurger to the rescue, pluggable into any ExceptionHandler.
> It cuts the first part of an exception chain if needed.
> It contains 2 properties:
> - alwaysEvaluatePrioritizedList: List<Class<? extends Exception>>: for example it contains "SQL504Exception", then any chain which contains that type of exception will be evaluated as the SQL504Exception instance.
> - alwaysTryToUnwrapList: List<Class<? extends Exception>>: for example it contains "WrappingServiceException", so it always tries to unwrap that.
> TODO: find beter names, suggestions welcome.
