in page number, chapter and outline numbering
in ~30 languages by integrating libnumbertext library.

- offapi: add linguistic2::NumberText

New NumberingType constants:

- ordinal indicators (1st, 2nd, 3rd...)

- cardinal number names (One, Two, Three...)

- ordinal number names  (First, Second, Third...)

Note: these numberings are parts of OOXML, too.

Plain text files of Libnumbertext's language data
are installed in share/numbertext (similar to
share/fingerprint), allowing further customization.
