[2.0] Customise circuit connection dialog

[pindab0ter]

I'm working on updating and improving the
UPS Friendly Nixie Tube Display mod. The Nixie Tubes are an extension of a Lamp, which means it inherits its circuit connection section as well.

What it looks like now

This is what I would like to achieve:

• Remove the lamp specific section (Use colors/Color mapping/Color components/Packed RGB)
• Keep the Enable/disable section
• Add a section where you can select the signal which value you would like to display on the nixie tube(s)

If possible, I would like to also open that signal selection dialog when you click on it when no selection is made, much like you get a dialog when clicking on an assembler that doesn't have a recipe set.

Can anyone help me out with how to go about this? I'm a software engineer so I'm well at home with programming in general. I got the mod to a state where it works. I'm just not familiar with the Factorio API and how to approach this.

What parts of this go in the prototypes? What part is runtime behaviour? What are the relevant parts of the API? How would you approach this?
