Another big lexicon reorganization.

    The lexicon used to be organized based on word classes (a leftover
    from SFST version) which is not necessary, and makes it difficult
    to include or leave out lexical entries based on criteria like
    colloquial use, obscenity, new/foreign words etc. This is just a
    reorganization the lexicon by making heavy use of preprocessing.
