Oflazer's analyzer to  TRmorph converter.

        This change adds the FST/scripts for converting between the
        analysis strings of Oflazer's converter and TRmorph. These
        were used earlier for converting available corpora that was
        tagged by Oflazer's analyzer for disambiguation purposes, but
        they may also be useful for other purposes.
Allow compilation of the manual without main .bib file.
Disable <perc> 'prefix' for numbers by default.
