This update focuses on one specific feature..
This feature has been requested a LOT.

At the moment, it only works with file configurations and is in Beta. It will though be able as default to get a lot of feedback.
You can disable it in your config by searching (Ctrl+F) for
Auto-Equip-Cosmetics

The principle is to equip back previously equipped cosmetics when:

• Rejoining the server, even if the server has shut down since the last disconnection.
• Coming back to a world where cosmetics are enabled.

Reminder: this feature is still in BETA. Please report any issue on Github: https://github.com/iSach/UltraCosmetics/issues
As soon as I get feedback from this feature and know it's stable, I'll implement a support for MySQL.

• Other minor bugfixes and improvements.
