Title: Make default job types redirect any output from the 'cd' command to /dev/null

RVM wraps the `cd` command, so when it changes the ruby version, it produces output like:

```bash
Using /home/ndbroadbent/.rvm/gems/ruby-1.9.2-p290
```

This is undesirable for a cron task that is configured to send emails, because we get emailed every time with that one line from RVM. So this commit silences every cd.

This is currently defined in our own `schedule.rb` file, but I thought it might be useful for others.
