Add a RSS link in social profile.

[googollee]

Hi,

I'd like to add a rss link in social profile and show it on the frontpage.

One solution is adding an option as params.social.RSS in config.toml (the value is the url/path of the rss), and add a section in layouts/partials/social.html as:

{{ with .Site.Params.Social.RSS }}    
<a href="{{.}}" target="_blank" rel="me noopener noreffer" target="_blank"><i class="iconfont icon-rss"></i></a>                                                                              
{{ end }}

I don't know how to add a icon to iconfont.css. Could you help to add that icon as icon-rss?

Thanks.
