Steve's Realistic Sleep

Added

• More configurability (by RickyTheRacc in #31)
  • sendDawnMessage: makes it more obvious that the dawn message can be disabled
  • showTimeUntilDawn: allows disabling the time until dawn in the sleep message, to allow for greater vanilla parity
• Russian translation (by 1-nkl in #36)
• Compatibility with Comforts' Hammocks
  • Daytime and nighttime is differentiated between in the HUD messages

Fixed

• Players get kicked out of bed slightly earlier than they should
• Amount of players needed to sleep message shows 0/X instead of the actual (non-zero) value
• After sleeping, the next weather change will always be a thunderstorm
