In game editing is now established! Wooo! In the future I'd like to add a UI to do it however for now you're going to have to deal with commands

Hopefully it helps to clear up any confusion since `tags.yml`'s are a little confusing at best. It also mirrors what core protect does so hopefully that'll make it more accessible.
- Made updating checking run asynchronously.
- Fixed a bug where reloading when the plugin was disabled would throw a `NullPointerException` This also occurred at shutdown.
- When 'out of bounds' on sending commands, no recommendations for tab fill will be shown instead of the player list.
- You can now use `/nametag info <tag>` to view all information on the tag as well as a preview.
- The main command, `/nametag` now has an easy to type alias `/ntm`.
- Added a create command for making new tags which are automatically saved to `tags.yml`
- There's a new edit command which allows the modification of tags from in game. Changes are also saved to `tags.yml`. No way to delete tags quite yet.
