This update changes many aspects of Nametag hiding, to make it much more trustworthy overall, as well as more user friendly.

-Both files have been merged into a single .sk file.
-Compatibility has been updated to work with 1.19.
-The use of variables to store the armor stands hiding the player's nametags has been stopped, as there is no need for them. However, temporary metadata tags have been used for the following purposes:
-Routine cleanup: every 10 seconds, any nametag armor stands not on a player are removed.
-When a player leaves and rejoins, his nametag will remain hidden
-When a server stops and restarts, players who had their nametags hidden previously will still have it hidden.
-Added a tab complete to the nametag command.

Have fun!
