Added Docker support (#40)

Browse source 
* Added Docker support

- replaced necessity for devicemapper (through kpartx) by using parted and
  losetup with offsets
- added Dockerfile
- added dependency for parted and grep
- added hints to README.md
- common: loop through unmounts, fix shellcheck warnings

* stage2: use debconf instead of console-setup patch. Fixes #41

## Docker Build
```bash
vi config # Edit your config file. See above.

```
If everything goes well, your finished image will be in the `deploy/` folder.
You can then remove the build container with `docker rm pigen_work`
If something breaks along the line, you can edit the corresponding scripts, and
continue:
```
CONTINUE=1 ./build-docker.sh
```

The build of Raspbian is divided up into several stages for logical clarity
