More powerful jQuery getScript with cache control

If you love getScript as a shortcut method in jQuery, but you hate not being able to control whether the script calls from the browsers cache or not then you can override the built-in function with a new one which is backwards compatible, so it won’t break any of your old code, and allows you to choose true or false to caching.

			cache: cache
	});
};

I had done some js but didn’t completely get it and began by copying and pasting from other sites in the hope that things would just work. Then again that’s how I started with php too.

As I began to work on PagePlay more and more the javascript needed to be more and more clean and easy to adapt for when we add new functionality.
