[New Plugin] IK and FK in Chara Maker

[Coppersocket]

There's a problem with bonemods, where when you enable IK in studio- sometimes it does not adhere to the settings you've made for the character. It'd be nice to be able to enable FK and IK in Maker, for two reasons. One, so you can test in maker to see what results you'll get in Studio, and two so you can pose the character in Maker for your cards.
