Updated to accommodate refactoring by Keen. Special thanks to Siro for making it quick and painless for me.

Pulled in the range to be closer to Vanilla -- this is now possible thanks to today's earlier updates

Drill processing cycles are now based on game updates, not real time

Cleaned up namespace usage to reduce mod breakage when Keen messes with duplicate interfaces.

Fixed alignment issue between drill target area in world coordinates and asteroid coordinates

Added a more spherical shape to the drill target area to make it look a bit smoother

Fixed an ambiguous interface error introduced in today's Space Engineers update

To avoid problems caused by the shape of the target area:
- extended range back to what it was at mod launch
- extended offset almost back to what it was at mod launch

Restored range of small drills to alleviate problems with drilling angles

Restored drill range to make for smoother trips through asteroids

Very slightly reduced range and offset of drills
Reactivated volumetric formula for calculating ore amounts
Removed modifier and randomness from ore amounts
