Reworked the Config system:
If you have an older version of the plugin, then the settings.yml config of the bungeecord / velocity plugin will be renamed to old_settings.yml and a new settings.yml file will be created (this is because I added comments to the config and also some new properties).
Make sure to reconfigure it!


Tab Completion:
The plugin now also has tab completion, which looks like this:


You can specify the completions in the settings.yml of bungeecord plugin.



Request Duration :
You can now enable request duration, which means that each request will expire after some time (you can specify the time in the settings.yml).

You will also see when the request will expire in the /friend requests command or in the GUI.


NOTE: You have to add %EXPIRES_IN% to the message and to the GUI to see the expiration time. (Or you can delete the messages.yml or gui.yml and it will be auto-created after that)

Extras:
There are a few more things I added and a few bugs that I fixed, check the settings.yml of the bungeecord plugin too see the new options!
