A list of more languages to be added to the oxt + a small simplification to the Mac link target for the oxt

The pull request contains two changes:

1. a small change to the linking target for MacOSX. I have not been able to get the original code to work, and the contained change does not seem to cause any issues, at least not on MacOSX 10.6 and later.

2. a request to add 60 new languages for libreoffice-voikko to recognize. With some regional variants added on top the total language-country combo count is 81. The languages are all being worked on in either Giellatekno/Divvun or in Apertium, both of which nowadays have builtin support for building zhfst files from their transducers.

A few of the languages have already been included in LO or have their own tickets for inclusion, the rest will be submitted after an initial discussion with Eike (erack at redhat piste com) about the best form of submission. Eike has been contacted, but has not yet responded.
