Short about localization

Just want to give some comments about localization.

If you want to localize this project to your native language just create locale short code named json file and place it to /mlp/static/locales. Use "en.json" as the reference as it is a fallback (default) language. Clear localStorage after json file creation and fully reload page - make sure that all files were reloaded (or clear all caches, files and cookies in web browser settings).

New locale will appear in language change user menu.

Dont't forget to make PR of new localization file ;)
