release-0.2

This release updates the client/server such that announcements are made to all connected-nodes when other hosts join/leave the VPN.

This can be useful if you wish to update /etc/hosts to add entries dynamically. For example I prefer to give my hosts a .vpn suffix:

 $ grep \.vpn /etc/hosts
 10.10.10.98  master.vpn
 10.10.10.99  git.vpn
 10.10.10.100 www.vpn
 10.10.10.102 mail.vpn
 10.10.10.101 blogspam.vpn
 10.10.10.103 debian.vpn
 10.10.10.50  frodo.vpn
 10.10.10.104 alert.vpn

See #10 for details of the implementation or the documentation in the supplied client.cfg file.
