[Feature] Sounds have been added for certain game events
[Feature] A countdown timer counts down to the start of the game. The timer starts when the `/sisr start` command is run. This allows chunks to load for players after they've been teleported.
[Feature] A new game option `delay` has been added. This sets how long the countdown timer runs for. Use `/sisr set delay=N` to set it. Can be set to any number between 10 and 60 seconds. The default is 10.
[Bugfix] Better inventory detection means all item obtaining events should be captured now. Please let me know if you find a way to get an item into your possession without triggering the end of the game!
[Bugfix] You can't `/sisr create` a game if you've already created one!
