As requested, I've added a way for people to apply custom model data to items.

But since the guns are all custom and not pre-made, I won't be able to pre-make the custom model data.
So for a solution, I've added /custommodeldata

(command requires "sn1perduels.admin.commands" or op)
- /custommodeldata get
- /custommodeldata set
- /custommodeldata remove

In the first post you guys were able to create custom guns using /creategun,
but in this update, you've guessed it, /createexplosives is here!

Basically shotguns are possible to make now
