Unwrap the library for testing
Include jQuery
Stub Backbone.sync
Convert spyOnLocalSync

The huge spyOnLocalSync used to be necessary in the node coffee sandbox,
but we can use a normal spy now.
Remove test_spec; was for testing the localStorage mock
Order the tests from lowest to highest level
localStorage returns null for nonexistent values

This was a bug in the mock localStorage implementation.
Fix integrationSpec with real localStorage

- localStorage.values does not exist, but localStorage.length does
- clear localStorage before the test to start at a known state
This "bug" doesn't happen anymore in a real environment
Update README with instructions to run the tests
