Multilingual brand/logo link switch

[jossemarGT]

Hi @AmazingRise!

I am doing my local testing to migrate from Beatiful hugo theme into yours.

I found that diary does not "auto-magic-ally" set the home link in the brand/logo area when you are browsing on any other languange that is not the main one. What I mean is, when I browse mysite.com/es (second language) the brand area link still points into mysite.com instead of the languange's home.

My questions are:

• If I want to fix it locally, should it put it under /layouts? If so what is the template/partial name I should look like? I think those are the sidebar and mobile-header partial templates so I will give them a try.
• In case I find a solution, do you have appettite for a pull request for that?

Thank you very much in advance.

I hope you see #106 fine. The change was trivial and it does not broke my local environment, but still I would like to have your input whenever you have the time.

Thanks again for this awesome theme, I just love it :)
