New version for 1.19! I've also decided to change the versioning so minor versions (like 2.X) are used for standard updates, and versions like 2.6.X are reserved for hotfixes and such.

Important changes:
- 1.19 support (note: only minimally tested)
- SQL changes, please make a database backup before installing!
- Update checker can now auto-update UC if enabled.

New features:
- You can now use color codes (with &) to rename pets.
- Update checker now notifies all players with the permission ultracosmetics.updatenotify
- Command for reloading messages only: /uc reload
- New command: /uc update which will update UC when an update is available.
- Some commands such as /uc menu are now allowed for everyone by default

Bug fixes:
