Additions
✔ You can now use a toggle that will show unowned prefixes to people in the prefix gui.
✔ /prefix reload will now swap out the /prefix command with whatever new command you specify in the config files.
✔ Added a messages.yml file to allow you to change all messages inside the plugin.

Bug Fix
✘ Fixed a new command name from not showing up in the tab completer (originally tab complete would still use /prefix).
