Adding project visibility to system hooks
Merge branch 'expose_visibility_in_project_create_service_hook' into 'master'

Expose project visibility in system service hooks

Our gitlab installation is currently setup with a system hook to ping our hubot. Currently whenever a project is created, hubot announces this, regardless of project visibility. It didn't really make sense for everyone to see this, and as the project visibility wasn't exposed in the JSON hook output, I thought I'd add it in!

As far as I'm aware, tests still run and pass OK. I'm not exactly rails savvy though, so any pointers/fixes/etc, please let me know!
