Pretty front page! And other pages!

This adds a bunch of styling and pages and junk. It also removes references to the already-deleted `utils.py`, which is important. It moves the settings file where it's supposed to be, and the outbreak bar updates correctly as the infection progresses. We'll need to add sass to whatever server we're using, to compile the `.scss` files into `.css` files. There are no tests added, because front-endd. This does fix a few tests (renamed url patterns broke them).
