* Better error message, when python client want to use wrong type of tag
value
* Refactoring of code
* Verse server creates special tag group in user node and this tag group
includes tag with real name of user (not username ... it would be
security risk)
* WIP: code refactoring: creating of node at verse server
* Make iniparser optional package, because it is hard to install
sometimes
* Bug fix: When client unsubscribes from node, then client is
unsubscribed from layers of this node too.

* Client can set its name and version number with
vrs_set_client_info(name, version). It will be used in info node about
avatar.

* Refactoring of Verse nodes at Verse server
 - No new features
 - Removed lots of duplicated code
 - Separeted some code from vs_node.c to vs_sys_nodes.c
 - TODO: do more testing (I hope that I didn't break anything)

* 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
