Release v0.0.0.17

When a mapped contact is deleted on one side, delete it on the
other side too (respecting sync direction setting):
- Deleted in Outlook -> delete in Starface (if direction allows)
- Deleted in Starface -> delete in Outlook (if direction allows)
- Deleted on both sides -> just remove the mapping
