Allow sphinxtrain to list stage names

Use sphinxtrain list to get stage names. Otherwise you have to go find the scripts or some logs to figure them out.

Thanks Kevin! A simple and very useful change ... I got really busy there and didn't have the bandwidth, sorry for the delay. I would like to do another SphinxTrain release at some point soon.
