Add bad behaviour system

Note: I tried updating this to the module system but I haven't properly tested this, this should be seen as a PoC'

Original PR from the GarageGames repo:
GarageGames/Torque3D#2120

Seems to work, but needs UI updates to play nicely with dark-theme and could use proper testing.

BadBehavior itself works fine and is easy to integrate (just copy the folder), I'm using it for years, the only problem is, that the UI does not work, so I created my behavior trees using my code editor instead of the UI inside the engine, this is the reason I hesitated to make a pull request of it into the main repo.

The issue with BadBehavior see here: BadBehavior/BadBehavior_T3D#2

I would just add it to the engine and have others fix the problem, I mean it is not the first unusable feature that was added to the engine without ever testing it.
