Add an option to set the working directory.

This makes it possible to simply wrap a command inside a container. This makes
it easier to use a container as an unified build environment.

Examples:

~/workspace/docker
$ docker  run  -v `pwd`:`pwd` -w `pwd` -i -t  ubuntu ls
AUTHORS		 Makefile	archive.go	   changes.go	      docker
[...]


docker  run  -v `pwd`:`pwd` -w `pwd` -i -t  ubuntu pwd
/home/marco/workspace/docker

Add workdir support for the Buildfile

For consistency the Buildfile should have the option to

Of course that is one option more to the buildfile,
so please tell me if we really want this to happen.
