Update trainer to support the updated evaluation framework

[lfoppiano]

This should fix the compatibility with the updated evaluation framework in grobid (PR, not yet in master: https://github.com/kermitt2/grobid/pull/280).

I tried to test it but the evaluation phase was requiring a file that is not in the repository, so I didn't really tested it.

I've added just a toString() because the new EvaluationUtils are returning an object. I think applying now should not break anything.

Super thanks !

After some tests, it appears that there are 3 System.out.println() missing to display the evaluation report string.

One in the main of SoftwareTrainer.java:

public static void main(String[] args) {
        try {
            String pGrobidHome = SoftwareProperties.get("grobid.home");

            GrobidHomeFinder grobidHomeFinder = new GrobidHomeFinder(Arrays.asList(pGrobidHome));
            GrobidProperties.getInstance(grobidHomeFinder);

            System.out.println(">>>>>>>> GROBID_HOME="+GrobidProperties.get_GROBID_HOME_PATH());
        } catch (final Exception exp) {
            System.err.println("GROBID software initialisation failed: " + exp);
            exp.printStackTrace();
        }
        Trainer trainer = new SoftwareTrainer();
        System.out.println(AbstractTrainer.runEvaluation(trainer));
        System.exit(0);
    }

And two in the main of SoftwareTrainerRunner.java:

switch (mode) {
            case TRAIN:
                AbstractTrainer.runTraining(trainer);
                break;
            case EVAL:
                System.out.println(AbstractTrainer.runEvaluation(trainer));
                break;
            case SPLIT:
                System.out.println(AbstractTrainer.runSplitTrainingEvaluation(trainer, split));
                break;
            default:
                throw new IllegalStateException("Invalid RunType: " + mode.name());
        }
        System.exit(0);
