Let recipe builders skip map build actions

[Zorbatron]

What

Allow a recipe builder to ignore a recipe map's build actions.

Outcome

You can make assembler recipes that use soldering alloy that don't have tin recipes generated, or make arc furnace recipes that don't use a fluid without oxygen being assigned automatically.

Potential Compatibility Issues

Shouldn't be any.

Recipe build actions are associated with a ResourceLocation in the recipe map - probably a good idea to have a way to only ignore a specific build action, in case some addon adds a second, important build action to some common recipe map. Might not actually be a good idea to have a way to ignore all build actions because of that case, honestly.

That's a good idea
