When playing back a cluster, it should start from the currently highlighted item.
This solves two problems with version 1.1: (a) you pause playback after hearing a word that might have been incorrectly categorized, and you want to hear it again; you click several words, then resume play; it seems strange for it to start anywhere other than the currently highlighted item; (b) after pausing you move some words around, then playback begins from position n+1, which is not necessarily the next word (because the list of words has been modified).
