Added makefile and made all containers buildable

[tpmullan]

I am interested in adding support for SOGo and want to gauge how well PRs are received on this project. I have made some very basic build files with the included Makefile that allows all containers in the project to be built. It will also build the all in one container. In the future I would like to see the mono container removed and the separate containers to become the standard since this will allow the application to be scaled. I have also added docker-compose files that make deploying to a docker engine server much easier.

I have also updated the individual service containers so they build, but doubt they are anywhere near workable. The only reason I am opening a PR at this point is the state is better than when I found it (following my do no harm mantra) and I want to know if it is even worth making the contribution. My proposed changes will be rather in depth and take me a decent amount of time / effort.

Let me know if you have any concerns with theses additions. If you are interested I will start working on integrating SOGo into the all in one container, then I will work on getting the multiple container setup working.
