Placing code + assets directly into Docker image

This radically changes the way we deploy to the production server, as a
Git checkout is no longer required there. All the necessary files are
now inside the docker image. As a result, /data/git should no longer be
mounted as a Docker volume.

- Renamed docker/build.sh → docker/full_rebuild.sh
  This makes it clearer that it performs a full rebuild of the Docker images.
- Full rebuilds should be done on a regular basis to pull in Ubuntu
  security updates.
- Removed rsync_ui.sh, we no longer need it. Other projects can also
  remove their rsync_ui.sh.
- Moved deploy.sh → deploy/2docker.sh and added deploy/2server.sh

deploy/2server.sh
