Add custom model in the node (shared extras)

Very useful for license plates: You can adapt it to use a separated model for license plates, so, who is playing that game can have your own license plate model (for example, the license plate of your country, or just the game default one).

Also useful for bikes with arms (very common on brazilian GTA modding, used by youtubers with first person mod). In this case, they can use your own arms.
