Allow quick save with Apply button

When adding new option values it is more convenient to be able to save
progress and stay on the same page (e.g. to reorder newly created option
 values). This button allows to do so, similar to how system dialogues
 would usually have an "Apply" button which saves changes but does not
 close the window.
