Fixed LPInjector registering to the Core
Stop MCChatListener from having multiple active instances
MinecraftChatModule.state instead of all the flags
Showing MinecraftChatModule enable/disable on Discord
/discord reset --> restart
Wait for each shutdown message to send on shutdown (although it hasn't really been an issue so far)
This means using Mono<?> in a lot of places
Also added a contract (IntelliJ) to warn if not subscribed
Faking getOnlinePlayers() is unnecessary and causes too much trouble
Today's work
