Version 2.4
- New boosts: Meet a specific category City-State, Be a Suzerain of a specific category City-State, Be a Suzerain of X City-States.
- Train Unit reworked for a custom boost, so the initial settler will no longer trigger "train a Settler" boost.
- Settle Capital on a Coast changed into custom boost, so it will not trigger after reloading for a different tech/civic.
