Add convenience methods to the recipe builder

[Zorbatron]

What

• Adds a few methods to the main recipes builder to make making recipes easier. Example: .fluidInputs(material, amount), instead of .fluidInputs(material.getFluid(amount).
• Adds a bunch of methods to the assembly line and scanner/station research recipe builder to make setting up recipe easier. Example: .researchStack(metaItem, amount) instead of .researchStack(metaItem.getStackForm(amount))

Potential Compatibility Issues

In the AssemblyLineRecipeBuilder, the .scannerResearch(itemStack) method used to make a new ScannerRecipeBuilder in the lambda when that lambda is already applied with a new builder. I don't see why that was there, but I could be missing the original context.
