Config/ID map update mirroring RU 2.2.1.0

Extra mods added again. Edit: twice!

Please note also that Metallurgy is configured to add ores above y-70 for a reason: RR 1.5.* had really boring mountains. I'd like RR 1.6.* to not repeat this mistake. :)

There appear to be some minor cleanup issues I didn't catch when publishing RU so there may be further changes. The only reason not to push them is for the benefit of any FTB forum users using the pack but I think that's pretty rare now.

Edit: I pushed these changes in RU 2.2.1.0 so that'll be fine now. Also I got GasCraft working, I was derping hard on that one.
