Fix projects page

Some of the css is not ideal (although justifiable), and the projects pages in general are far from complete.

However this is enough to merge into master. It's a lot more that we currently have, it has pictures, and it's responsive. Also the html structuring is repetitive, but that can be remedied at a later date. 

@brotatos You should fix the projects blueprint though, as "projects.html" doesn't exist anymore.
