[GUI] Empty moddable containers inside vanilla GUIs

[LizardOfOz]

What?

Add empty containers to vanilla GUIs that could be populated by mods.

Why?

I was making a mod where it'd make most sense to add extra information to the Crafting Machine's panel of the UI, rather than creating a dedicated side panel.

You can kinda sorta do that by abusing negative padding, but it's obviously an unsupported hack that will break if multiple mods would try doing the same thing, and those UI elements can't be interacted with.

Having dedicated containers for mods inside the vanilla GUIs would be a "good enough" solution for most mods, while, presumably, not being more difficult for Wube to implement than the existing custom UI stuff.

+1, some flow to add elements inside machine gui would be useful in many mods. Even if its just at the bottom of all vanilla elements. Like relative guis, but not in an box on the side which looks ugly for some things.
