Create base template for sub-sections of knode.io

This is the starting base.html for knode.io sub-sections. We need to determine what map we'd like to use and the styling will need further guidance.

Once we have the context in place, I'll move forward(or need help) with rendering the templates and adding the templating into the html. When that happens, I will breakout the html into list.html as well to keep the base nice and clean for reuse.

The idea is for us to be able to reuse these.
