NEW ADDITIONS - The ClassSelectionGUI is now configurable! To an extent anyway. You can now edit the messages in the GUI, not the item or slots though. This is due to the GUI being the foundation & focus point of the internal code for the plugin. Editing the items would require a full recode, in which I do not want to do. - A new file has been created called classSelectionGUI.yml where you make your edits to the GUI. - This change came through as a way for people to translate the messages.
