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!

Remove markdown syntax from notification emails

Merge request notifications once again gained markdown syntax 😄 In my opinion, markdown should not be present in emails because it is not rendered - it looks funny. I fixed this once before in 57ad81a9 and it was recently changed back to use the markdown style.
