Including Kaldi results

[syhw]

I intend to put the best and baselines Kaldi results, e.g. from https://github.com/kaldi-asr/kaldi/blob/master/egs/wsj/s5/RESULTS for WSJ, for all datasets. Those numbers are not always supported by publications, but I believe they are still indicative of what can be achieved / reproduced. Thoughts?

Please add a column "reproducible" then, I think everyone will agree this is the right step to scale this up.

Yes, see #32 :)
