is (a) pretty feeble, and (b) means that although Net seeds transfer between platforms and still generate the same game, there's a suspicious discrepancy in the typical seed _generated_ by each platform. I have a better RNG kicking around in this code base already, so I'll just use it. Each midend has its own random_state, which it passes to new_game_seed() as required. A handy consequence of this is that initial seed data is now passed to midend_new(), which means that new platform implementors are unlikely to forget to seed the RNG because failure to do so causes a compile error!
