*
* Notably, **Google** does this (for example, maps.google.com), which I find rather strange considering
* that I'd expect them to be among those telling us to feature-detect.
*
* So, use this class to generate a pile of turd that looks like every other browser out there acting like
* every browser that came before it so we get the "real" version of pages when we browse.
