substantive rework of af_ZA hunspell

[kris]

Hi

I would like to submit new Afrikaans Hunspell dictionary files (Eg af_ZA.dic and a_ZA.aff).
The current files have not been updated since 2009 and are outdated.

I have done a total revamp of the two files.
Details on the update is described here in Afrikaans: https://puzzlefoundry.com/wiki/af/AfrikaanseHunSpellToetser

The files are gzipped to af_ZA.tar.gz under this pull request:
 https://github.com/LibreOffice/dictionaries/pull/15

How do I go about it?
