[Request] Prerequisite Groups

[Foxy_Boxes]

Okay so a simple concept: Stuff can be grouped together for the purposes of requirements.
For example, if you had Automation-2 require "Automation-Group", then anything defined under the list of "Automation-Group" validates the requirement.
But not just limited to technology: Say you were crafting something that required an Inserter. That's fine. Until you have a mod that adds inserters that are supposed to be the same just operate different (e.g. 90* inserters). You have to have a basic Inserter, you can't use the mod's one. However, if you had a group "Basic-Inserter-Group", the mod could simply add their inserters to the list and players could use that as a crafting requirement.
