Expose the possibility to attach a terminal to the started container

I am working on a framework to coordinate integration tests for a number of containers that are configured as docker images. For that I am using docker-java 0.9.1 and have found that (some) of my container die immediately after they have been started because there is no terminal attached to them.

To overcome this I have patched docker-java 0.9.2-SNAPSHOT to expose the withTTY method for container creation. I will create a pull request for this issue.
