tiAuth

1. Added compatibility with standard SHA256 (not AuthMe)
2. Fixed a bug that caused the player to be redirected to the backend server on Velocity

1. Added support for version 26.1 of the virtual server

[2] Added database migration from nLogin
[3] Added support for versions 1.21.10/11 for the virtual server
[4] Added the /auth forcepremium command to forcefully enable/disable premium mode
[5] Added a cost setting for Bcrypt hashing
[6] Fixed a bug with the popup dialog window during /changepassword
[7] Fixed a startup issue on standard BungeeCord (non-forks)
[8] Fixed an issue where the /changepassword and /unregister commands would freeze/hang if the entered password was too long
[9] Fixed the "Invalid signature for profile public key" error when changing UUIDs for premium players
[10] Fixed an issue with the max concurrent players limit per IP
[11] Fixed an issue where the proxy wouldn't shut down upon a database initialization error

And probably a few other minor things I forgot about.
