This arranges all emitters in an SDetailView with some customization.
Primary benefit of this is that hooking things into the UI will require almost no work and elements can still be customized for a good UX.
Previous UI is still available and should work exactly as before.
Quite a bit of refactoring was needed to acheive this but much of it was needed for other things anyway and/or has some nice additonal benefits.
E.g.
- All constant types are supported easily.
- You can now create a default data object in the graph which will propagate through to the effect editor.
- Adding new data object types will be very easy.
Also added a delete and duplicate button for emitters in both UIs.
