Adding simple logging helper on listeners, for fast debugging.
* Call `serializedObject.Update();` before `OnInspectorGUI` in the editor script in order to update old value when changing value.

Some minor refactoring - renaming variables
Clean up in `RegenereateAllAtoms`
Use `OnEnable` instead of `OnAfterDeserialize` when setting inital value for variable. `OnAfterDeserialize` was causing major issues with the custom editor, eg. it did run when focusing a Variable and showing the inspector, basically making it worthless to change or even inspect the Variable at runtime. `OnEnable` is only called ones when the ScriptableObject is loaded in runtime, which is what we really want. This has been tested running in the editor and in builds.
Add missing editors scripts `TouchUserInputVariableEditor`and `SceneFieldVariableEditor`
