Initial Structure - Githubissues

Finished the initial infrastructure and added all the static sections to the site. Some notes about this PR:

I did most of the work on Sara's macbook (to be able to use Sketch) and that's why a lot of commits appear as done by Sara.
I did not embed the fonts yet because I do not have the files. I installed then on my computer and I'm guessing you have them installed in yours too.
Didn't start working on the responsive styling, so do not open the page with a phone yet.
