revert mining changes

[Dr Zoidcrab]

Having pod mining tools available at round start makes every other mining tool and miner obsolete. You can still make pod plasma cutters at ship component manufacturers, it requires one block of any power source. Industrial suits require uqill and claretine, you can make three suits with one block of uqill, and claretine isn't hard to come by. Use explosives if you dont want to mine by hand.

It would be nice to get some anti-radiation or anti-toxin meds in mining like cog2 has. There are medkits for healing the burn damage though.
