Develop 1.10.8 (#140)

* Add support for TikTokLinkMicBattleItemCard for battle/match power-ups
* Switch to an efficient pool of daemon threads instead of thread per websocket and sleeping!
* Implement Eulerstream send chat API endpoint!
* Add static to fields for single instance to manage all heartbeat threads. Far more efficient than 1 thread each sleeping!
* Add global comment to known its a true global singleton!
