remove divergence from upstream since patch has been accepted
Merge branch 'runlocal' of git://github.com/elelay/syncserver into runlocal
remove unused browserid.xxx properties, use localhost

- using localhost instead of 127.0.0.1 out of consistency with the other
  services
- specifying an audience is better
