Adjusting tiredness

[skeyuui]

there are three fatigue systems in the game, here's how they work

• rogfat, which is actually the green stamina bar
  -- the one that goes down when you run and recovers quickly
  -- does not affect need to sleep
• rogstam, which is actually the blue fatigue bar
  -- the one that goes down when you chop a tree and recovers when you lie down
  -- does not affect need to sleep
• tiredness (the important one here), doesn't seem to have an indicator?
  -- gets increased by 1 at every life tick, goes from 0 to 100 in about 3 IC hours
  -- gives you the tired debuff at 21 IC time if tiredness >= 100
  -- only way to reduce it is sleeping with the debuff

this PR changes

• tiredness increases by 0.33 every tick (around 9 IC hours from 0 to 100)
• (new) sleeping reduces tiredness, reducing more more if you sleep on a bed (bed 45; no bed 25)
• (new) characters start with 45 tiredness so they will likely have to sleep at the first night

tldr you wont get the tired debuff if you slept a bit before nightfall
