Small option property cleanup (#3577)

* Notify change listeners

I can't come up with a reason for why we would not want to do this

* Remove the Display Type for OptionProperty (only used in ImGui)

* Replace extra boolean with internal anonymous addOption function

* Tiny refactor

* removed dropdown on a couple of more places

* Update optionproperty.cpp
