Adding social medial links

[iamjillsanluis]

• [x] Facebook
• [x] Twitter
• [x] LinkedIn
• [x] Update the Call to Action blurb (I'm no marketing person so need assistance on this).

Steps:

1. I used social media icons available from http://lipis.github.io/bootstrap-social/
2. I generated the links using https://seocentury.com/share-link-generator/

The link generator did not have Instagram. I am not an IG user, so need to poke around how these new cool kids does it. As a result, I pushed that work in #29
