Fixes a number of issues users have encountered.
- More strict with minimum age for pairing of couples
- Fix bug with traded items counting towards maintain item orders
- Fix for crash at world generation screen. Added option for world generation quality (try setting it to low if the game is still crashing at world gen).
- Fix for soft lock when rescuing unconscious colonists. Should increase performance of other save games too, there was an issue with too many "Rescue friend" jobs being created when colonists got injured.
- Fixed issue with being able to trade with the same trading party multiple times. Should now only be able to trade once with each trading party.
- Reduced wild plant reproduction rate
