Blogposts and Social-modifications

Added blogposts!
The Social-constructor keeps the styling and classlist of the htmlelement
it's replacing.
Merge branch 'master' of https://github.com/Iteam1337/docpad-gulp into social-master

Conflicts:
	src/partials/github.hbs
	src/scripts/dynamic-content.js
Forgot to add the blog-related content
