UI - CS View City (GK)
Compatibility: G&K required, Hot Seat
Adds a list of "protecting" players to the City State Greeting and Trading popup dialogs
(Also added a button to centre the map on the City State - hence the name - but that was removed when the functionality was added to the core game.)
Changes the City State greeting (CityStateGreetingPopup.lua and CityStateGreetingPopup.xml) and trading (CityStateDiploPopup.lua and CityStateDiploPopup.xml) core files, so incompatible with any other mod that changes these files
