Hey, folks. I've just merged an internationalization support to master. If you'd have a free minute, I'd appreciate if you could add a translation in one of the languages you speak.

Adding a translation

1. Add a respective locale file to this directory: https://github.com/Redd-Developer/howurls.work/tree/1b37709eb7a8b443633c31d16d29a9587886539c/src/locales. Please use ISO language codes for file names.
2. Provide localizations for all the keys you can find in en-US.json. When in doubt, feel free to ask here, or in the pull request.
3. Add a new language to the <select> element in the language selector component:

   howurls.work/src/components/LanguageSwitch.js

   Lines 23 to 25 in 1b37709

   	<option value="en-US">English</option>
   	<option value="uk-UA">Українська</option>
   	<option value="ru-RU">Русский</option>

   . Please give it the value prop equal to the name of the locale file from the previous step.

You can preview your localization locally by running:

$ yarn install
$ yarn start

Please let me know if there's any questions. Thank you!
