Add static pages

[sarimabbas]

As per title, add the following pages (and more, if relevant):

• About
• FAQ
• Partners

These pages are separate (i.e. not from the dashboard but stand on their own). To create these pages, follow these steps:

1. Look over Design Team work in the Drive
2. Create a new branch
3. Your templates must live in client/templates as their own .html files. You will likely not need to use any components. Make sure to extend layout.html
4. Your CSS must live in client/static/css/<page_name>.css. You may also make use of the styles in client/static/css/global.css
5. Your images must live in client/static/img/<page_name>/<example_img.png>
6. Copy over work from the thinkspace-web repository, if any. But the templating system is DTL, not Jinja2, so you may have to modify accordingly. Take a look at https://docs.djangoproject.com/en/2.0/ref/templates/builtins/
7. You may edit the navbar and footer links to reflect the new pages
8. Test locally (see the README), push to branch and create a pull request
9. Comment pull request link here

That's it. Thanks!
