RetroShare/libretroshare/src/services/p3channels.cc
drbob 1efe8a2cb1 Added Authenticated Forums. This required quite a bit of
additional functionality in other places, including:
 * add Sign / Verify functions to authxpgp
 * sign/verify messages, and control flags for p3distrib/p3forums.
 * add authmgr to p3distrib etc.
 * added AUTH flags to rsforums interface.
