Changed what the placeholder %player_next_rank_exp% displays back to what it originally displayed
Added the placeholder %player_next_rank_exp_difference% which shows the difference between player exp and next rank exp
Added an option in config.yml to allow players to build! (Enabling this removes the editmode command)... This can be helpful if you want to allow players to build plots or something somewhere! (Maybe a special map)
For the users that downloaded 5.2 update your scoreboard placeholder %player_next_rank_exp% to %player_next_rank_exp_difference% in messages.yml (Or as usual lol let it generate by it self)
