Submission system created

Now you can submit costumes to the required amount for a chapter. You can put costumes on, and take them off with very similar logic as the storage system. You can only submit when the minimum requirement of a top and bottom, or full piece, is met. The image below is the layout of the UI. Everything is currently placeholders, which the rest of the project will be mostly a lot of drawing assets, so the demo is close to being ready!

Main changes:

• Requirement costume amount added
• Clothing pieces can be placed as a child of the mannequin
• Clothing pieces can be sumitted towards the final costume count
