ngram and suffix_list: still up to date?

Hi @pneff 

regarding the `KEE` example, are the [ngram/en.json](https://github.com/squirro/training/blob/master/kee/ngram/en.json) and the `suffix_list` inside the [config.json](https://github.com/squirro/training/blob/master/kee/config.json) still up to date?

Thanks.
