Allow Configuration of Default Actions, Conditions, and Controls

[moccajoghurt]

There are several default actions, conditions, and controls that shouldn't be used in my project. I'd like to configure the btproj file to hide them in the editor.

I'd like to express my appreciation for Groot2; it's a fantastic tool. At the moment, I haven't upgraded to the pro version because my behavior trees aren't generating sufficient revenue. However, I definitely plan to purchase it in the future.

By the way, I'm exclusively using Groot2 and not BT.CPP. This tool is truly outstanding, and I believe it deserves recognition as a standalone project. Currently, I utilize it to construct behavior trees for video games and have developed a custom C# parser for the XML files.
