Human Improvements - v0.7.0.28

Just a few little improvements with your human workers, as changes here due to the waste addition to the game. Humans will now visit crew quarters from time to time to use the bathroom facilities. This will create the new waste resource, but currently this is just vented to space. I've also added in the wander recreation exercise to human workers (was previously just visitors).

Also note a fix for human workers repeating recreation type more than expected. I found your human workers were addicted to just dancing near the jukebox! ːsteamhappyː

Patch notes:-

• Humans now visit crew quarters from time to time to use the bathroom.
  
• New waste resource added (from crew quarters and canteen). Currently just vented to space.
  
• New vented message type for resources that need collecting but no storage (waste/co2).
  
• Waiting for toilet negative morale addition. Increase negative morale modifier for more extreme problems (starving/no air).
  
• Human workers can now choose wander recreation type.
  
• Improve: Character now moves off item if idle.
  
• Fix: Repeat recreation tracking incorrect. Too much dancing!
