create base image with eatmydata support
Thank you for creating the whalebuilder. However by default apt/apt-get/aptitude are extremely slow, so I use custom image for whalebuider instead of the default image.
```
# Docker Image for Debian Development
# docker build -t debdev -f debdev.docker .
# This image can be used for whalebuilder
FROM debian:sid

```
Or should I submit a Merge Request?
