add docker link
add tank submodule
add twp.oauth submodule
Get basic Dockerfile working

The provides a fedora base with nginx (on port 80) talking to
uwsgi which runs a very simple wsgiapp.py (that 'Hello Worlds')

An image is built with:

    sudo docker build -t cdent/tankdock .

And that image is run with:

    sudo docker run -t -i -P cdent/tankdock /bin/runner.sh

Figure out the forwarded port with

    sudo docker ps

This will get more automated and will have ONBUILD commands
for custom oauth and other settings.
