Error:

```
Failed to remove container (rsyslog): Error response from daemon: Unable to remove filesystem
```

`make test_integrations` requires > 2Gi of memory

How: 1) we start syslog docker container 2) all other containers use
syslog logging driver to ship their logs to that container

[docker] move to alpine base image

Improve CircleCI setup (WIP)

- update docker machine version to 0.9.0
- save coverage.txt as artifact
- save docker logs as artifact
- test if coverage.txt exists
- 2>&1 redirect stderr to stdout in tests

813Mb => 29.5Mb

Rename docker image to tendermint

permissions error during make dist

```
mv: cannot move ‘./build/dist/windows_386.zip’ to ‘./build/dist/tendermint_0.8.0_windows_386.zip’: Permission denied
```

The main reason is people usually expect docker image to have the same
name as the repo. Plus, tendermint is cleaner than tmbase.

tmbase would make sense if we had multiple docker images within
tendermint, but we don't.

- 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)

Otherwise:

```
panic: runtime error: index out of range

goroutine 1 [running]:
panic(0xbb8de0, 0xc82000e080)
        /usr/local/go/src/runtime/panic.go:464 +0x3e6
main.main()
        /go/src/github.com/tendermint/tendermint/cmd/tendermint/main.go:48 +0x811
```

- mute most of the commands
- replace github.com/tendermint/tendermint with just "."
- introduce PACKAGES variable
- delete unused NEWLINE

Refactor Node; Node is a simple BaseService

Merge release-0.8.0 to develop
