- Potential fix for empty objects getting created in wrong places when copying prefabs

- Added support for namespaces inside the extra copier types json. For example: { "categoryName" : "Prefabulous for VRC", "typeFullNames": [ "Prefabulous.VRC.Runtime.*" ] } ` Will add all Prefabulous Avatar components.

- More copier logic fixes. - Maybe fixed nested prefabs not copying?

- Copier logic fixes

- Rewrote copier logic. It now matches objects based on nearest parent humanoid bone. This will hopefully fix issues with stuff not copying correctly. Or it will cause more issues! - Added ability to copy skinned mesh renderers again because I don't remember what that broke and why I removed that on two separate occasions. I guess we're about to find out for a third time.

- Added undo support to copier and a bunch of other buttons. It might even work!

- Added VRC Head Chop component to copier and destroyed. - Added VRC Constraint components to copier and destroyer. - Fixed avatar info throwing compile errors outside of vrchat projects. Thanks @NotAKidoS - Fixed some small ui bugs

- Probably fixed vrchat constraint beta errors - Removed ignore list from copier ui since it doesn't work anyway - Added chilloutvr cck and magica cloth components to the external section of the copier, thanks @NotAKidoS
