PumkinsAvatarTools

• 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.
