Added functions:
I added a reload command and also a message that you can change in the messages.yml. Also support for 1.17.1 is added to this version so 1.17.1 is 100% working with this version, and I recoded some files/functions so the overall code is better and faster.

Needed steps to do for updating:
1. Stop your minecraft server.
2. Go to your plugins folder.
3. Delete the current Prefix-1.0.jar
4. Open the Prefix folder and remove the messages.yml file.
5. Add the new Prefix-1.1.jar into your plugins folder.
6. Start your minecraft server and enjoy the update.
