Demo not working on chrome

http://dynmeth.github.io/RaphaelLayer/

On console

```
Refused to execute script from 'https://raw.github.com/dynmeth/RaphaelLayer/master/dist/rlayer.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. 
```

You should provide the file in the gh-pages branch..
