Slightly improve taxation infrastructures

Levy Administration costs 570 prod, yields 3 money on Main Plaza. That's very bad, one should never build it. How about this? Levy Administration costs 280 prod, yields 3 money on Main Plaza and Administrative Center. Somewhat better, still very far from OP or "must have".

Taxation Office costs 1600 prod, yields 5 money on Main Plaza and 3 money on Luxury Resource deposit. How about this? Taxation Office costs 1000 prod, yields 5 money on Main Plaza and Administrative Center and Luxury Resource deposit.
