use three dots instead of unicode character

No idea what the root cause is, but if I run devdocs via the following commands:

    rvm wrapper 2.0.0 ddocs rackup

and then

    cd /path/to/devdocs && ~/.rvm/bin/ddocs_rackup

I get the following traceback:

```

If I just run it from the command line with `rackup`, no error. However, changing the ellipsis to three dots fixes the issue by making the file ASCII compliant.

Would like it if someone could advise why running via launchctl generates an encoding error, where running from the command line is fine.
