The following has been tested:
- Disconnect from menu -> DISCONNECTED
- EssentialsX kick -> KICKED
- Suspend server JVM -> DISCONNECTED
- Suspend client JVM -> TIMED_OUT
- Call #exceptionCaught -> ERRONEOUS_STATE
Suspension was done through `kill -STOP` and subsequently `kill -CONT`
after the player has (been) disconnected.
Closes#254.
