Summary:
This helps forcibly end mocha tests when they hang, and print out
something that may help debug the situation.
Also add the generated static/bundle.css file to core/.gitignore.
Also, avoid using npm-packages-offline-cache when building core, by avoiding use of .yarnrc which turns it on.

Summary:
This adds a two-stage Dockerfile for grist-core. The first stage builds
Grist, and the second collects all files needed to run Grist.
The resulting image is about 600 MB which is quite a bit bigger
than it needs to be, but seems fine for now when the first goal is
to establish that people can open and edit Grist files on their
own infrastructure.
The image uses stock python rather than our sandboxed python for now.
