Hot Fix - EA Update v0.5.0.11

I just knew i'd let some silly bug slip through after concentrating far too much on all the human code. I broke building items, with changes to worker modifiers! ːsteamfacepalmː

Although have managed to get a couple of human improvements in as well.

Notes:-

• Heal icon added to character icon function
  
• Crew initialise not all levels at 100%
  
• Fix: O2EfficiencyBuildItem, charType unknown
