/usr/bin/node^M: bad interpreter: No such file or directory

Apologies, pull request #398 did not do the trick.  With version 0.12.6 as downloaded from NPM, I still see the following error when trying to run `eask` as a script:

```
/usr/bin/eask: /usr/bin/node^M: bad interpreter: No such file or directory
```

I have worked around this by running `dos2unix eask.js`, but I thought it was worth mentioning in case it causes other people difficulties.
