Moving forward with sdk tools

Working on Dockerbuild based solution for installing wrappers onto
image (as opposed to mounting shared dir). Init subcommand works, except
that downloading dependencies fails, as rabix isn't deployed to pypi
yet. Once project is initialized, `docker build .` should take care for
the rest.
pep8 fix
Fixed packaging

When installing this package using pip, setup.py failed because
requirements.txt wasn't included i package
Project init

rabix-sdk command has an init subcommand that prepared dependencies,
build files and produces Dockerfile. Final image can be built by running
`docker build .` This way sdk is cross-platform as biuld works with
boot2docker by copying files to docker image.
build script cleans up after itself
Back to distutils for lib

Tested on bare ubuntu with no pip. Only problem that remains is how to
get rabix-lib tarbal into projects build directory.
