Trying to explain the workaround that's currently needed to make - in particular - SimpleComponents show their API doc in the NEI usage page, I realize it's more terrible than I thought. So I'll want to add an explicit system for registering ItemStack -> Environment resolvers (or rather ItemStack -> Object for SimpleComponents, since they only become Environments at runtime when the OC class transformer runs).

Something like

interface EnvironmentProvider {
  Object getEnvironment(ItemStack stack);
}

and allow registering thos in api.Driver or so.

This would deprecate the EnvironmentAware interface (would still work in 1.6, but I'd remove that in 1.7 then).

Feedback welcome.
