* When client is authenticated at Verse server, then Verse server
creates special node as child of avatar node of authenticated client
 - This node contains information about hostname, time of login, client
name and version of client
 - Client name and version is negotiated with Verse server during first
phase of Verse handshake
 -Fixed bug: vsession->peer_hostname is initialized correctly now
