Work on launch command and make fixes:

  - [x] bug in not adding command to new containers => create new dockerfile
        which will be used to start container
    - [x] distinguish between image cmd and container cmd =>
          `cmd` in buildfile will be used while building. Can be overriden
          via `launchCmd` when running creating and running a container.
    - [x] Change some of the make commands which don't use `-f` but have it
          as part of the make command name
