Fixed and updated specs

This PR includes a mix match of:

* fixed failing IE
* updated specs syntax to use the new expect/to syntax
* updated specs from using the soon to be removed ```be_true``` syntax to either ```be true``` or ```be_truthy``` depending on the assertion
* updated a few specs to use ```stub_browser``` instead of stubbing the same methods over and over
* removed empty parenthesis, we are using ruby after all
