Added i18n support for malagasy language (MG)

Hey dude,

first of all, thanks a lot for the great work you did on Lila : it's just awesome in so many ways (code, UI and so on).
Now to show you my support, I would like to contribute this little something : i18n support for Malagasy (MG - Madagascar) language.

Feel free to drop me a message if you need me to review some stuff.

thanks a lot and have fun...
