Too OP new buildings

[Mikifor]

Hey bro

I played with your mod much time and really like it. That's cool that you still update it.

Imho the new buildigns are too OP for good balanced FFA game. Can you rebalance it or accept some pull requests?

For example Mushroom Farm. It gains really mush food with a few maintenance. I think it should be okay to replace current effects with:

Mining: +1 food from mountins, maintenance: 1
Engineering: +1 food from hills, maintenance: 2
Civil service: +1 food from forests, maintenance: 2
Education: +1 food from jungle, maintenance: 2

Waiting for response if you accepting pull requests.
