🛠Improvements & Changes

• Supply lines always provide energy and oxygen
  
• Supply lines can only connect to other supply lines or structures that have both power and oxygen
  
• Power routers that provide power and oxygen to connected structures now show a white bubble at their center
  
• A visual hitch resulting from redistribution of power through lines when placing a new line or a new structure has been significantly reduced, and in most cases no longer exists
  
• Supply lines now have a minimum distance with other supply lines and additional feedback is shown when placing a line if it is too close to another line
  

📝Additional notes

• Current supply line placement will still work even if it violates the new minimum distance rule
  
• While the supply line refactor is a big performance improvement, there is still a separate hitching issue resulting from general power distribution through power routers that needs to be addressed. This patch is effectively half the problem solved.
