make Lua Node Editor an addon for ultra engine

[Kai_Ma-401]

I did some reading about the flow graph and that's supposed to be you guys vistal scripting I think? it just not all there for ultra engine yet I was thinking making Lua node editor an add-on would give you less people biting your heads off for not having visional scripting and its under GNU GENERAL PUBLIC LICENSE so I think you can do whatever you want with it.

Looks interesting! Our flowgraph system is meant for setting up sequences of events that occur in a scene. We may add more features to it later, but it probably won't ever be a full visual script editor. The problem with these systems is often that they seem easy in very simple cases, but as you add more code they become more complicated than normal code.
