Translations

@sibamohanty I moved your changes to the translations branch, just FYI. I'll comment on stuff here soon
I am looking into http://i18next.com/ as romain suggested. I am not sure though how to fix up the overflow of translated text and thus affected UI elements. One thing that comes from top of my head is identify such strings which are bigger in size and have a different styling for it. Probably Gus can give some pointers on it.
