Title: Make .env file collection robust against cd output

This pull-request redirects any output from `builtin cd` to `/dev/null`, so it doesn't end up in `_files`. This is needed if people have set up `precmd` or `chpwd` in zsh to output something, [e.g. to update the terminal title bar] (http://alenitchev.wordpress.com/2006/09/17/zsh-and-xterm-window-title/).
