The Inspector is probably setting window.$ if window.$ is not global by default

@thejameskyle reported that w/ his app jQuery is being set by the insepctor inside of core.js.

We should clean this up:

Here's the naive solution we came up with the other day...

if (typeof window.$ == "undefined" && typeof window.jQuery == "undefined") {
  // @include ../../lib/jquery/jquery.js
   this.$ = $ || window.$ || window.jQuery;
   var $ = this.$;
   delete window.$;
   delete window.jQuery;
} else {
   var $ = window.$ || window.jQuery;
}
