* "injectJs()" now supports ".coffee" input
* "injectJs()" is now available for the "phantom" object as well
* CSConverter is now a singleton embedded in the Utils static class
* The code used by "injectJs()" is now centralised in the Utils static class
* It includes a script in the page
* It uses a callback to ensure any code dependent on the include runs afterwards
* It uses the signal "javaScriptAlertSent" to do the trick (is there another way to be notified of the "onLoad" event from outside the page context?)
* It uses a "private" slot "_appendScriptElement" to pass the script url in the page context (is there a better way?)
* click() accepts a "querySelectorAll" input - can click on multiple things in one call
* loadJsFile() is synchronous at loading JS in the page
* added 2 examples in JavaScript to show how to use (and test) the new methods
* NOTE: someone will have to generate the .coffee version - I tried using "http://ricostacruz.com/js2coffee/" but it hangs and I'm not willing to learn why :P - I don't like Coffee Script.
