Subject: Fix add data operation not working correctly

Reminder: do not get reference to hash map value... duh

Add thread-safe logging (log is in order now!).
Store data immediately to database when WE add it instead of waiting for
response from remote peers.
TODO: Test with multiple peers (not only localhost)
