Provide debugger value presenter for ScriptableObject

The debugger extension provides additional value presenters for certain types, including `Behaviour` and `GameObject`. There should also be something for `ScriptableObject` derived classes, mostly to indicate that it derives from `ScriptableObject`. Perhaps show `name` and `hideFlags`? Is it possible to replace the type presentation in `agentConfig = {AgentConfiguration} Hoverbuggy (TowerDefense.Agents.Data.AgentConfiguration)`? Maybe something like `{AgentConfiguration - ScriptObject}`?
