First version of automatic contact discovery.
TODO: - Configuration (much of it) - Enabled by default? - Which keys to import? Current state: All non-revoked and non-expired with matching userid - Search for keys if already known? Current state: yes, may cause traffic (configuration: only when wifi?) - Update interval: Currently Android handles it, might be good (causes automatic refresh on new contact and stuff like that) or bad (too many of refreshes)
