More refinements to the orthography generation. We've now decided that we should base the orthography on the hyph rather than the pron, because that way we can perhaps insert intrusive schwas more easily; morpheme boundaries appear to be significant for this purpose. I'm also orthing the phonemic phrases in citations, and since these are partly hyphenated, I'm handling them slightly differently, splitting on the morpheme boundaries, but using the same conversion code. I have a hook in for the schwa insertion if we can formalize the rules for it.
