slimmed down docker container (#356)

- use intern container to run webpack + ts build and then copy over the build results to final container
- moved some build deps over to devDeps to slim down runtime deps in final container
- added build + dep folders to docker ignore  (only matters for building locally, but asserts that only the built files are used in the container)
