Added an option of using the <Interpolate /> with a raw HTML

[KostyaEsmukov]

Discussion in #189

Usage:

<Interpolate i18nKey='foo' useDangerouslySetInnerHTML={true} />

TODO:

• Tests? I'm not sure how to properly test a component, see my comment at test: add tests setup + coverage + travis #193
• Generate dist files

did you init i18next before using it?

[KostyaEsmukov]

In my own project? Yes I did, and it works as is. Why do you ask?

In case you need my config, here it is:

import * as i18n from 'i18next';
import * as LanguageDetector from 'i18next-browser-languagedetector';

import { ru } from './ru';

i18n
  .use(LanguageDetector)
  .init({
    fallbackLng: 'ru',
    whitelist: ['ru'],

    debug: ENV !== 'production',

    interpolation: {
      prefix: '__',
      suffix: '__',
      escapeValue: false  // not needed for react!!
    },
    joinArrays: '\n',
    resources: {
      ru: {
        translation: ru
      }
    }
  });
