This is a big update! Check out the following improvements:

• Move saved waypoints to separate config file waypoints.yml
• Store waypiont as a serialized Location class instance
• Store user UUIDs instead of player name (now it will work when users change names)
• Store and display biome of saved waypoint
• Continue to store player name in separate key for easy visual editing of config file

Because this plugin stores the Waypoints in a new separate config file waypoints.yml your old waypoints will not work in this new version. But, it's definitely worth the update, this version is considerably improved. I've learned the right way to store the waypoints and this will hopefully be the last time I introduce a breaking change to the waypoints save file.
