To match other .js loading patterns in this repo, don't use a CDN angular, but rather a local copy in case examples are used offline or in large classrooms with slow internet. Also updated to latest angular 1.4
This patch makes some optimizations in the result service's image;
- switch to `node:8.9-alpine`, which a smaller base image
- use `https://` for the registry
- use `COPY` instead of `ADD`, following best pracice
- cleanup npm cache, and combine steps to reduce image size
These changes bring down the image size from 248MB to 81.2MB
