Subject: LDAP refactored behind interfaces. All functions of LDAP now hidden
 behind interfaces: Authenticator, Lookup and NextKeyManager (LDAP property
 storage was already a ClusterStorage). Gateway holds additional objects, and
 Fixes #26 #191. Refs #27 (needs additional work for read perms and auth
 tokens)
