wip : Mining.

So what is working now : 

1. Buy mining drones at commidity market (i know strange place)
2. F3 Mining GUI, just a quick orbital info and goto surface AI command and mine deploy.
3. Miners descend and starts shooting at ground.
4. Mines and collects "ore" based om metallicity
5. Persists thorugh jumps and back
6. Miners can now mine when you're not in the system. so you can run a mining op in several starsystems at once.
7. miners tell when they are full
8. Miners return to you if you are within 20km when full to offload then starts mining again.
9. Alot to be done.. like GUI ... Prospecting.
