fix: Removes BodyValue and fixes modifying Body and BodyMod in props gump. (#743)

* Removes BodyValue
* Removes BodyPicker gump
* Fixes setting Body and BodyMod in props gump
* Props will now look for an `implicit cast` in order to find a way to allow you to modify values with the props gump.
* Fixed `[self set body 0x190` so it works too.
