Where are the contrib plugins?
The contrib plugins setting seems to be missing, you can't add Slack or Hipchat integration in the settings like suggested here: http://taigaio.github.io/taiga-support/contrib-plugins/hipchat-integration/
Could it be the readonly conf.json? Ok I just checked, there is no plugins folder anywhere. Do you think it's possible to include the contrib plugins in the next update?
