[.23] International Measurements (Metric and more!) 1.2.1

This mod adds settings for international measurement systems in XCL.

Support for the following features have been implemented for character creation, examine yourself at night, and at the New-U machine
Imperial and Metric systems for height and weight.
The following bra measurement systems have also been implemented: US, UK, France, Italy, Europe, Australia, and Japan.
Also added is the ability to show the character's ID, as I find that useful.

This should support modded MCs (tested with Kendra) 

Thanks to Aph for making the game we all love. 
Special shout out to McLurkington for pointing out when I'm being stupid or overthinking things, and for teaching me things even he's not trying.

And thanks to everyone who wrote code that I referenced when looking at how something works
