Scenario syntax for selectively removing entities and recipes

[byorgey]

Currently, scenarios can define custom entities and recipes that should be available in addition to all the "standard" entities and recipes. However, it would be nice (and hopefully not too difficult) if scenarios could have even more control over what entities and recipes will be available. For example, what if you wanted to

• Create a scenario where using a harvester is not allowed, so the player has to be very frugal/precise in their use of available resources?
• Create a scenario with a completely different set of entities?

Concretely, I propose

1. There should be a way to remove specific entities by name. e.g. perhaps within the entities list you can put something like no: harvester or delete: harvester instead of describing a custom entity. Like this:

   entities:
     - name: thing
       ...
     - no: harvester
   

   I guess we'd have to parse such a thing as a list of "entity map edits" instead of directly as a list of entities. Alternatively, we could just have a separate top-level list of entities to remove.
2. There should also be a way to completely clear the list of standard entities, like a top level boolean field standard-entities.

   standard-entities: false
   entities:
     ...
   

   You could use this if you want to design a custom set of entities from scratch.
3. Likewise, there should be a way to remove specific recipies. Since recipies aren't named you would just have to describe the recipe you want to remove.
4. Also likewise, there should be a way to clear all standard recipes.

I think the above is a bare minimum, but we might also consider adding more nuanced ways to edit the available entities and recipes, such as allowing some sort of filtering or wilcard matching (e.g. "remove all entities with the substring drill in their name", "remove all recipes requiring iron gear as an input", etc.)

This idea originally came out of a discussion here: #831 (comment) .

Maybe we could support wildcards when removing entities and recipes.

Being able to remove all recipes that for example produce drill could be useful.

the idea was mentioned of not allowing players to use a harvester

I think that was in #831

So as a concrete proposal, how about this:

• There is still only a single entities key and a single recipes key, which contain lists of objects
• Each object can be either
  • An entity or recipe description to be added
  • The key remove, containing a nested entity or recipe record, except that not all fields are required and fields may contain wildcard patterns

For example:

entities:
  - name: foo
    properties: [portable]
    ...etc.
  - remove:
      name: *drill

recipes:
  - <regular recipe 1>
  - <regular recipe 2>
  - remove:
      out: [*, branch]
