	/* The following "hack" was suggested by Andrea Giammarchi and adapted from: http://webreflection.blogspot.com/2009/11/195-chars-to-help-lazy-loading.html
	   NOTE: this hack only operates in FF and then only in versions where document.readyState is not present (FF < 3.6?).
	   
	   The hack essentially "patches" the **page** that LABjs is loaded onto so that it has a proper conforming document.readyState, so that if a script which does 
	   proper and safe dom-ready detection is loaded onto a page, after dom-ready has passed, it will still be able to detect this state, by inspecting the now hacked 
	   document.readyState property. The loaded script in question can then immediately trigger any queued code executions that were waiting for the DOM to be ready. 
	   For instance, jQuery 1.4+ has been patched to take advantage of document.readyState, which is enabled by this hack. But 1.3.2 and before are **not** safe or 
	   fixed by this hack, and should therefore **not** be lazy-loaded by script loader tools such as LABjs.
