[Scripts] Achievements test filler script

[JWepi]

Simple interface which will save in a .csv file with a specified format a list of achievements

[db0company]

• [x] Define a csv format to store the achievements collection (Achievement element detailed here: http://life.db0.fr/api#h.2ujx0461t1dw)
• [x] Find an OCaml csv lib
• [x] Create an OCaml script that will parse this csv
• [ ] Use the OCaml API library (read the part "User corner" for full documentation of the lib) to add the achievements on the API
• [ ] Commit this script and the csv file on this repo

I don't think we need any interface.
