Move all start up config into "HostConfig" when doing a container create #72
Change to using HostConfig in container "create".

As of Docker 1.4.0, host configuration in Docker start is deprecated. So we switch over to the new way of providing the host configuration as part of the "create" container step. This is available since remote API v1.15 (Docker 1.3.1 or so, I believe). Fixes #72
