#39

Describe the feature you'd like

Replace the pack field with contribution storage with a packs array. For now, this will always just have a single pack in it, but this will faciliate cross-project contributions and is an easy step to do right now.

Screenshot(s)

interface CurrentContribution {
	date: number; 
	pack: string;
	authors: string[];
	texture: string;
}
interface ProposedContribution {
	date: number; 
	packs: string[];
	authors: string[];
	texture: string;
}

Notes

This will require a decent number of things to be changed:

• Gallery modal author tab
• Submission bot contribution adding
• Texture lookup for gallery and slash command bot
• Webapp contribution form
• Decent amount of the API
