Temporarily disabled SSL, it doesn't work between java and C++-based
implementations (python, c++).
Fixed a bug in per-user-servant-locator - it assumed the session was at
least in the session manager's table (that is, at most expired, but not
yet purged from the table). This caused NullPointerException for invalid
sessions.
Pretty much completed C++ client. Features missing:
  - spam implementation, maybe later
  - client-side fault tolerance - not present in java, we'll see
