SAMMI Rpg System v1.1.0

This is a small hotfix that adds a new command and fixes an issue.

• Added a new command “Update Alias”
• Fixed a typo in Level up

WARNING: There is no filtering, someone can change their name to anything, even if the message gets held by automod, use this with caution! I intend on making a better solution for updating aliases in the future but for now, I’ve added a command to let you update aliases. It is your responsibility (for now) to make sure names are not obscene.
