Fix conflict with different version number

Hello, I use your script in one of my current project.
I had little problem today morning with bower, cause in bower.json is different version number than in tags on github.com in Parallax-ImageScroll repository.

Now if I will install it with bower, I get
```
bower checkout      Parallax-ImageScroll#0.1.0
bower error         Invalid Version: 0.1
```

If you can merge this pull request, it would be awesome and bower will be happy to ;)
