Patch 0.8.5.4 - Performance boost and one fix!

So, the weekend is here and I want to have the best possible version out, and I think this is it:

• A few performance tweaks that might be very noticable at big and/or very cluttered settlements.
• This should also fix "Not enough resources" popping up a little to often.

Best wishes, lots of love and enjoy your weekend! =) //Mattias
