Put some spawners in the shop

Small suggestion but there were spawners in the shop in beta. A few new players have joined now and asked about this, and were frustrated when it wasn’t offered. The shop is a little dry overall anyway, and I don’t think putting spawners in there would throw off the balance. It would also give players a more clear goal to work towards initially, and would help balance the economy so that rich factions or p2w players wouldn't be the only ones with spawners. This would **have** to be done alongside balance changes to core placement and spawners, which there are other suggestions for. Primarily, letting new factions place a limited number of spawners without a core.
