Make the ValidationException a little bit less mutable than before. All
its dependencies are now passed into the constructor.
This commit also make the Factory pass the translator to the exceptions
allowing to define the translator before the exception gets created.
This change is not the ideal one, later I would like to not need the
Singleton from the Factory to do that, but for now it seems like a good
approach.
One more thing that this commit does is to introduce the "id" for
Exceptions. Key can be either the defined "name" or the name of the rule
that throwed the exception. This method will be handy to identify
exceptions better.
