Major Menu Update:
Over 1000 lines of code added for this update.

New:
- Added Nation Menu GUI
- Added Nation command prompts
- Added configurable lang option for Back button and lore
- Added new /nm command
- Added townymenu.nation.use permission - this can either be added via Permissions plugin
or within the townyperms.yml

Update:
- Updated some lores and menu titles
- Updated dependencies where required

Preparation:
- Preparing to add HeadsDatabase to menu icon options (might take a while)
- Looking to implement the Towny CommentedConfiguration in the future so yml files will not have to be reset

You will need to reset your settings.yml and any localization files you have loaded like 'messages_en.yml' etc
