Cloned body parts don't inherit texture effects

When a node is cloned (say from armor with all the skinned parts), it will not inherit the NiTextureEffect from its parent node when present. This causes problems in mods such as this https://www.nexusmods.com/morrowind/mods/44189. The environment map effect will not show on any of the armor defined in the skins NIF, since the NiTextureEffect is relative to the Bip01 node and does not propagate to cloned child nodes.

Morrowind.exe does not inherit all node attributes from the parent node like NiAlphaProperty, NiFogProperty, etc... so NiTextureEffect seems to be handled specially.
