Several external links use insecure protocol (http)

[kcarboni]

There are several links in this template that use http rather than https. Chrome at least warns about the insecurities this may create. I would like to see those links changed to https.

Examples:

README.md

[Freelancer Jekyll Version](http://startbootstrap.com/template-overviews/1-col-portfolio/) is a Jekyll build for the Freelancer portfolio theme based on [Bootstrap](http://getbootstrap.com/) created by [Start Bootstrap](http://startbootstrap.com/).

_includes/footer.html

<div class="footer-col col-md-4">
  <h3>About {{ site.title }}</h3>
  <p><a href="http://startbootstrap.com">Start Bootstrap</a> is an open source library of Bootstrap themes and templates.</p>
</div>

I would be happy to submit a PR to fix these

Same issues!.
I am using this template on my project, but after deploy the website on google cloud platform, there are privacy errors.
Look forward to hearing from you.
