Very low prio: /set killtime

[SnakThree]

Done. A pull request will be created later today, after some minor code formatting cleanups.

• First death, no timestamp
  
• Second death after enabling them, timestamp
  
• Third death, global death messages were turned off. Diemessage is still turned on, but no timestamp because you can't see the death.
  

If chattimes are enabled, you shouldn't get duplicate timestamps. Haven't tested that, but theoretically in the code it shouldn't. - This change was given to someone running a private server. If they tell me I screwed up, I'll make a quickfix before the pull request.

Happy stamping

Bumping this because it went unnoticed and undocumented.

/set dietime on
