This sets us up with a build system that compiles the frontend HTML, CSS and

JavaScript, as well as makes some changes to the config loading to be able to

pull out configuration from the environment instead of a local file.
This is primarily oriented towards deployment on Heroku, since they have a free

tier that handles what we need, but it should be pretty applicable to any

Node.js hosting.

Did a bunch of builds and verified that everything was correct.
Deployed!
