Allow for annotating blueprints with same icons as the map g

[EpicPartyGuy]

TL;DR

Allow the map gui icons to be placed in blueprints to show what inputs are expected where.

What ?

When downloading blueprints from other players, it's not always obvious what materials are expected on which belts.

Why ?

Allows for easier sharing of plans and lowers the learning curve for someone new to multiplayer/Factorio.

I like this idea.

In complex blueprints I use constant combinator with signals configured to show what is expected at input/output points. It takes a bit of extra effort to remove them on blueprint placement. A bit annoying
