Remove github theme dependencies

[eduxstad]

In preparation for moving the site off of github.io (#4), we need to remove the dependencies on the github Jekyll theme and provide them ourselves. It's unlikely that we will complete a full redesign before the transition, so this would act as a stopgap in the meantime.

We have two options:

1. Just take the CSS stylesheets over and use NGINX
2. Install Jekyll on the server and host the site that way

EDIT: Due to the temporary nature of this I feel just copying over the site directly without Jekyll would be easier.

I agree. I don't think we need Jekyll. In the future, we probably won't be using it anyway (I think).

Ok, when I get some time I'll copy over the site. If any of you want to do so feel free.

I have removed the dependencies on github.io themes.
