Subject: [PATCH] update Dockerfile

- update golang to 1.7.4
- version as env variable
- change DATA_ROOT from /tendermint/data to /tendermint (it's not just
  data that gets stored in DATA_ROOT; we create data folder on start; as
  a result we get /tendermint/data/data, which is confusing)
- remove noninteractive env vars (do we really need these?)
- remove nodejs dep (some apps may require nodejs, but core is not one
  of them; it was convenient before, but now I believe we ought to
  remove it because other people who are using java do not want a
  bloated container with nodejs)
- build tendermint inside a container (once again, it was convenient
  before, but now I am testing kubernetes and I don't want to wait every
  time TM compiles)
