Title: Use new image name format for Docker 0.7 compat

This removes deprecation warnings that occur during `git push`. The `buildstep` script called `docker commit` with an old-style image name:

```
[DEPRECATED] The format 'CONTAINER [REPOSITORY [TAG]]' as been deprecated. Please use CONTAINER [REPOSITORY[:TAG]]
```
