Move Future Society data to App.Data and leverage it to reduce redundancy

1. Move Future Society data into App.Data.FutureSociety.
2. Remove App.Data.misc.FutureSocieties (which is directly redundant with App.Data.FutureSociety.playerFSNames).
3. Replace hardcoded mutual exclusion code in arcology datatype cleanup and rival FS adoption with dynamic mutual exclusion based on the FS mutex data.
4. A couple small FS system fixes
