Replacing 'cluster' with 'syllable' when comments describe certain Indic shaping behavior (#563) 

* Clarified wording of syllable/cluster behavior in Uniscribe in final_reordering; changed one other probable typo.

* Additional syllable/cluster swap in comments for final reordering and for initial-reordering matra decomposition.
