Improved global effects

[SWeini]

TL;DR

More freedom on global or per-surface effects to not need hidden beacons that often.

What?

What we currently have:

• LuaSurface::global_effect
• some TechnologyModifier, such as lab-productivity, lab-speed, mining-productivity, recipe-productivity

These offer some possibilities (exactly what was envisioned for space age), but not enough for many mods. I'd like to see some of those:

• imaginary modules that affect one (or all) surface(s) for one (or all) force(s), but only if that module is allowed in that entity - basically like a single hidden beacon with infinity range, but not interacting with any beacon profiles.
• TechnologyModifier for those imaginary modules in addition/instead of runtime scripted
• TechnologyModifier for per-recipe speed/consumption/pollution changes (not just productivity)
• TechnologyModifier for per-building speed/consumption/pollution/productivity changes (could also affect non-crafting entities, e.g. mining drills)

Currently LuaSurface::global_effects completely ignores any effect restrictions set in place by entity or recipe. Would also be great to make this configurable somehow.

I would also appreciate a way to add effects (via mentioned methods or via normal modules) that do not contribute to the "one and only" +X% pool, but instead work independently, e.g. a +30% speed effect that would always multiply the speed by 1.3 instead of changing 500% speed to 530% speed which is barely noticeable.

Why?

Hidden beacons do work, but they are a burden to set up. They also make the compatibility between mods a lot more difficult, e.g. when moving an entity with picker dollies the hidden beacons has to move as well. All the hidden beacons in mods that I know of are used to simulate global or per-surface effects.
