History
Stefan Weil 1c7e00611b Add initial support for traineddata files in standard archive formats 
This requires libarchive-dev.

Tesseract can now load traineddata files in any of the archive formats
which are supported by libarchive. Example of a zipped BagIt archive:

    $ unzip -l /usr/local/share/tessdata/zip.traineddata
    Archive:  /usr/local/share/tessdata/zip.traineddata

     23468070                     21 files

`combine_tessdata -d` and `combine_tessdata -u` also work.

The traineddata files in the new format can be generated with
standard tools like zip or tar.

More work is needed for other training tools and big endian support.
