Compatibility with SimpleConstruction

[RobotGuy]

Hi,
I was trying to replace EPL with SimpleConstruction in my current game but found that it had issues working with SandCastle based on the errors coming from B9PartSwitch. I notice others have had this issue.

I worked out a patch that seems to fix the issues and at least passes a smoke test.

• It fixed the B9PartSwitch on the RocketParts container to us the SimpleConstruction tank types to get the ratios it uses and the base volume to prevent it working like a Tardis and better match the large holding tank in SimpleConstruction
• It adds a new EL_ConverterRecipe that uses Ore rather than MetalOre (on a like for like bases) and adjusted the recipe to account for the differenct densities. It will convert the same amount of Ore/LF/EC to Metal as it did MetalOre/LF/EC to Metal in the same time. The conversion rate is slightly less than the SimpleConsrtuction Convert-o-tron but much faster unless you have a 5* engineer on board.
• Patches the smelter to use the new recipe, switches out the MetalOre resource container for an Ore one and removes the ScrapMetal to Metal conversion

I'm sort of new at his but that patch appears to be okay. I don't know what would happed if you switched EPL to SimpleConsrtuction while having the Smelter or the SandCastle RocketParts container being used within the game.

Please feel free to include it if you find it appropriate.

(BTW this was against the SimpleConstruction-4.0.99.7-prerelease)

Also, sorry I wasn't paying attention and missed seeing the same issue as issue#3
