Mining mounts and making resources different

[civ2buf]

Mainly I just wanted some way to make the bigger satellites useful, because I was going to change the size of the remote miner or the satellite so the first satellites fit.

In the normal game, satellite research is too expensive to reach the right size of satellites for remote mining in time to use it.

The neat thing about Alpha Centauri that I'd like to see in SE4, is the crawlers that go everywhere for resources. If satellites were useful for remote mining without tons of research then you could have asteroid only systems that were hotly contested.
