Update Annotator and jQuery to latest versions
Remove sinon-chai library

In favour of just using the standard sinon assertions.
Update all tests to use sinon assertions
Update touch.coffee to work with latest annotator

We now piggy back the Annotator#onAdderClick() method and only append
our own range and quote object when the initial annotation is created.
This works around issues created when the onAdderClick method was
changed to also trigger the "annotationCreated" event.
Update package version
