v2.1.0

Breaking changes ⚠️
Note: This is a release focusing on updating the user system, to allow every user to have a uid and use uid to identify users, rather than using discordid.
Warning⚠️: Major database structure updates involved, backup the database before upgrading to this version.
Hint: It's no longer necessary to place an upgrade.py in the directory to upgrade, the upgrader is coded into the main program, which will be executed automatically.
