Make app deployable to GAE

We'd like to be able to build and deploy topeka, designer, and the tutorial separate from the docs repo itself. Having to build all of these apps within the same project is creating too many blockers and makes the docs repo complex for folks who just want to set it up and submit a PR.

This change adds an `app.yaml` and `deploy.sh` to this repo. It also checks in the vulcanized files so anyone running `dev_appserver.py .` won't get a blank page.

At the moment it requires a bower resolution to install some of these, and we get complaints from confused folks who are new to bower and don't understand what that means. It also means that the app can break from day to day, depending on when someone checks it out and runs bower install.

I wanted to float the idea of having these on whatever the current stable tag is, so it's easy for people to just check out and bower install.
