Configurable background color from python code (POC for space view properties from code)

[Wumpf]

What

This is primarily a quick exploration of our ideas on how to log blueprint from (python) code. It worked all well and arrived in a shippable state!

The next thing to figure out is how we streamline this with codegen while still preserving all the flexibility that is demonstrated by the different ways of constructing Background3D here (construction as well as component name).

Great time for feedback on the general direction!

Looks good, but probably deserves some sort of docs, e.g. a snippet

Yeah we need to figure out a system of snippets & docs for space view blueprints in general. I'll note down a few things in tickets and add it to the planning

I love how straight-forward this is!

My only question is if we want to formalize calling these things "properties"... I don't have a better name but this name will show up a bunch of places as a generic building block for all space views so we should at least think about it a bit.

we talked about this on our daily and it looks like "(Space) View Properties" is sticking around :)
