vagrant, build, openid updates

- fix wallah submodule version. Not sure WTF broke.
- bin/go build nicer output progress
- automatically download node.js distro if missing for build
- switch openid2 provider from livejournal to yahoo
  - livejournal does not provide https
- use ansible shell provider to provision the vagrant build box. Much
simpler. More worky.
- use process.title module
