Migrated CSS framework from MDL to Bootstrap 4
So I rewrote the site using Bootstrap 4 instead of MDL. This is a WIP, just decided to push this to get feedback on design or if anybody wants to work off of what I've done so far.
- Colors are missing
- Navbar doesn't correctly show active link
- Bootstrap is being included using a MDN link, we should problably download it and include it as a dependency to improve loading times.
