Default to creating new places items globally
The Places panel in general is global, with its contents shared across all apps that use it. However when you manually create a new entry using right-click > Add Entry… the resulting dialog defaults to creating an app-local item that won't be shown in any other apps or the file dialogs.
Other methods of creating items such as drag-and-drop create items globally; only this method does it locally.
This violates the otherwise-global nature of the Places panel, so it isn't the best default. Let's change it.
