Multiple things have changed with this version
Config "SayMessage" changed to "PlaySleepMessage"
Config "Messages" changed to "SleepMessages"

Added following config options:
# Play a different sleep message for each player.
#Default: false
DifferentSleepMessages: false

# Play different message for each player when time skip is canceled
# Default: false
DifferentCancelMessage: false

# Play different message for each player when time is skip
# Default: false

Added bit of code to catch when a sleeper gets disconnected from the server for any reason so they are not included in the count of sleeping players.
