Advancement Announcer v1.3 - The GUI Update!

This version introduces a complete GUI overhaul for the in-game editor, making configuration easier.

Key Changes:

• Full GUI Editor: Create and edit presets & auto-messages entirely through the /aa edit GUI.
• Deletion Confirmation: A new confirmation screen prevents accidental deletion.
• Smarter Update Checker: Now correctly compares version numbers (e.g., 1.10 > 1.9) and only notifies for newer versions.
• Fixes & UX Improvements: Fixed the renaming bug, improved multi-line message previews, and added better input validation.
