new event TabCompleteRequestEvent and deprecate TabCompleteEvent

Players with permission bungeecord.multiple_connect can have multiple connections with the same Minecraft account.
The UUID and player name is altered to avoid collision with other player:
UUID : xxxxxxxx-xxxx-VIxx-xxxx-xxxxxxxxxxxx
- The UUID version (V above) is now the provided version + 8 (for online player, it is 4, so it becomes C).
- The I digit will follow the index of the duplicated player : first duplicated player is 1, second one is 2.
- The name of the player will be the real player name, followed by the character "." (dot) followed by the duplication index.

Bedrock accounts connected using the Floodgate plugin will not be able to connect multiple times due to the risk of xUID collision.
