- Allow OptionButton selection to be set to -1 to signify no selection, both via API and in the editor.
- Reset OptionButton selection to -1 when the selected item has been removed.
- Fully convert PopupMenu to a zero-based ID system, which improves an inconsistency in generated IDs when making new items in the editor.
