opentyrian / need-data.sh

[Alexandre Detiste]

Hi,

Here is my rewrite of need-data.sh into C code for OpenTyrian package.
(I also included notify-send in the mix).

This first need that this pull request is approved
https://bitbucket.org/a-detiste/opentyrian/commits/12c763dc1ca049825e928a8a417812d55c44bcf9

I will then propose this to upstream, with
"These can be installed using game-data-packager.\n"
changed to generic
"Please read the README file.\n"
