* Added "db" module group to deal with database management tasks.

* First module: file_db to store filename, fingerprint (md5sum) and basic
  stats (mtime, size). Additional fields can be specified as well.
* Will use sqlite as the backend for now.
* API is rather generic so the underlying database engine can be replaced.
