Add better structured variable support to DialogueTree extension

[blurymind]

I am thinking of adding something like this in dialoguetools

It will enable storing actor stats or inventory in a structured way, that can then be used for implementing UI in gdevelop.
So if you do this in yarn:

// init
<<set $c.tom.outfit = work_suit>>
<<set $c.maya.outfit = winter_coat>>
<<set $c.tom.mood = happy>>
<<set $c.maya.mood = sad>>

to build a HUD in Gdevelop, you will be able to dig into "c" and loop over all existing characters ([tom, maya]), then you can loop over each stat ([outfit, mood])

Keeping that stuff in yarn state greatly simplifies persisting it and kills the possibility of copy pasta errors

experimenting with this now in a javascript event - i was able to extend the dialogtools functionality without even running gdevelop in dev mode, which is excellent :D

It does work very nicely, but i am hitting one pesky limitation: Gdevelop's ui extension framework doesnt allow custom expressions to return an array
@Bouh @4ian is that something that is there but hidden? I wonder if there is a way around it?

is this advances nested variables functionality in yarn state something that would be beneficial to pr to gdevelop?
I just wonder if its worth spending the time to create a demo and make a pr to dialoguetools to add these extra utility methods/expressions I am making..
