Modify paths of dependencies in examples

[Eddie Dolan]

All of the examples reference jQuery.js, jQuery-UI.js, underscore.js, and scrollstory.js as if they were in the /examples folder. It would make it much easier to run the examples if the paths were changed to reference where the files are stored in the repo (src/ bower_components).

I'm happy to make the changes and submit a pull request if needed.
