As stated [here](https://github.com/codingteam/codingteam.org.ru/pull/50#discussion_r84912875), we need to update Telegram icon on our [Resources](https://codingteam.org.ru/resources) page to [this](http://fontawesome.io/icon/telegram/). We're using some free CDN to download font-awesome now through [CSS import](https://github.com/codingteam/codingteam.org.ru/blob/a74cb026fc6eeb31546633419d6f87c3fd15097a/wwwroot/style.css#L2). This CDN doesn't provide font-awesome 4.7.0. Font-awesome [recommends](http://fontawesome.io/get-started/) to either register on their CDN by email (and I don't want to manage this registration at all) or download their files and serve them from our server. Probably we'll want to go third way: [download these resources from npm](https://www.npmjs.com/package/font-awesome) as part of our frontend build pipeline _(note that currently we have no pipeline at all)_ and incorporate it into our CSS through `@import`.
