Subject: [PATCH] Auto-reset mappings when address book is changed in profile
 editor

When editing a profile and switching to a different Starface
address book, the old contact mappings are invalid (different
Starface IDs). Now automatically clears mappings and shows a
notification. Custom address books are already listed as tags.
