Hopefully not too controversial. Essentially allow overriding of our default analytics/javascripts template behaviour.

I'm not sure I definitely see why you'd want to override these chunks (yet - sure there is a good reason !) ?

So this all came out of the request to be able to print automagically print an area of the page.

Putting google analytics at the end of a page to get round our proxy problems is fine, but window.print has an implicit call to document.ready so will never complete if the analytics code is present.

We are appending a page onto the main page when we do the window.print. We therefore do not want to call the javascript twice (as its called on load). It also seems like a sensible thing to be able to override.
