Changes:

• Categories have arrived! Make multiple kinds of shops!
• Added a separate directory for shops to avoid confusion.
• Code cleanup
• Added new methods to the API
• Changed lang.yml
• Changed shop.yml (This is now the categories menu)

Thank you all for the amazing feedback and reviews. However, I don't think I'll be posting free resources for a while. If you like my plugins and would like something private add me on discord (Skript#0001) and we can discuss something.
