Now, if an item in the Main Menu does not have the same name as a help section, clicking it will do nothing and will no longer produce an error in console.
I updated the default configuration to properly explain the way that entries are now shown on the menu (alphabetical based on entry name). No need to update if you're already using the plugin, it's just so that new users understand it and are not fed conflicting information
I forgot to fix this when I implemented the back functionality into the plugin (allowing you to go back to the main menu by clicking a border pane or an item without a command). Sorry about that...
