Regarding #147 Also added new eslint deps for what is coming. Breaking: polyfills are handled differently now.

* The frontend dependencies are now cached in the docker images itself
* A little hack is used to restore them when needed ie: the `node_modules` folder is stored outside of the workdir and then brought in
* Images are now versioned on the registry
* The docker-compose file has been updated to use the new/versioned images.
* The documentation has been updated.
* And the Gitlab-CI has been tweaked.
