Update the source of the examples

[WebCloud]

Probably the LSAdapter should be included on the source codes as a separated js file: https://raw.github.com/rpflorence/ember-localstorage-adapter/master/localstorage_adapter.js

Even though the code examples here work, trying to replicate them from the latest version of emberjs will fail as the model will not be successfully parse. I researched and found that other adapters, other than the native fixture adapter, will have to be loaded.

This fixed my issues.
