StarterPack grants the ship listed in Vessel on first login and puts it in the battle slot when put_in_battle_slot is 1. credits/goldCredits/tokenCredits here are extra wallet gifts on top of the gold_on_start/credits_on_start cvars in ConfigureShard(). defName must be a real ship def or the new account spawns broken. For a generous localhost give credits here plus gold_on_start in Lua; both stack. Only affects newly created accounts.
