Add a civ bonus for seleucids: Farms -25% resource cost, -75% build time.
requested to merge real_tabasco_sauce/0-a-d-community-mod-unit-specific-upgrades:sele_civbonus into main
Summary
Seleucids have no civ bonus and are in need of one.
Rationale
The bonus is historically justified and seems of interest to gameplay. It should pair nicely with sele's high food demand. (Justify the change, possibly highlight risks) possibly OP, but maybe not.
