This is a merged port from /tg/station and Virgo on logging standards.
The diary has been replaced with GLOB.world_game_log, diaryofmeanpeople
is gone (because it wasn't actually used) and a whole bunch of logging
procs have been changed to optimize Splunk.
This commit adds the Nightshift lighting mode from /tg/. From 19:00 to
07:00 in station time, the station will go into a reduced-lighting mode,
with dimmed lights across the station.
In conjunction with this, there is a new configuration option to start
the shift time at a random time other than 12:00, so that players are
more likely to experience a night shift (as opposed to having to have a
7 hour round).
