WARNING, TIMIT BASELINES CHANGE BY THIS COMMIT!
The change is in how the PER is computed. Previously there was optional silence with no output symbol, and forgiving of silence deletions. This was however slight cheating (Traditionally in TIMIT, the silence is scored).

The change consists of:
- removing the optional silence from he lexicon (see call of utils/prepare_lang.sh in run.sh)
- removing the forgiving of 'sil' deletions from scoring (see change in local/score.sh)
- updating the RESULTS

From now on the PER scores will involve no cheating and will be comparable to experiments in the literature.
