* Simplify handling of occlusion types in editor code
- Unify updateIONoteInEditMode(), setOcclusionFieldInner() and
setOcclusionField() into updateOcclusionsField()
- Don't use `includeInactive` property of Shape class in editor code
- Drop `isEditMode`
+
Update the occlusions field every time a mask or text is updated, not
only in editing mode but also in adding mode, so that IO cards can be
previewed correctly in the card layout screen
* Indicate current occlusion type in pop-up menu
