Jquery in closure

I was running into an issue wherein the $ was being hijacked by prototype.js.  The specific error I was getting was:

$.Deferred is undefined in Backbone.Model.prototype.fetch()

The issue was solved by including jQuery in the main closure of backbone.fetch-cache.

I regenerated 	backbone.fetch-cache.min.js .

I also made sure to run the test suite by calling `grunt`. Tests passed with no errors.
