#693 Add "security type 18" to security protocols

[Romano Giannetti]

Since the last upgrade of my server to Gnome Desktop 3.10, I can connect with TightVNC only with encryption disabled.

The error given is:

[ 5872/ 6448] 2014-01-20 12:11:18:247 List of security type is read
[ 5872/ 6448] 2014-01-20 12:11:18:247 : Security Types received (1): Unknown type (18)
[ 5872/ 6448] 2014-01-20 12:11:18:247 Selecting auth-handler
[ 5872/ 6448] 2014-01-20 12:11:18:247 + RemoteViewerCore. Exception: No security types supported. Server sent security types, but we do not support any of their.

I am looking for a server-side solution for the short term, see http://askubuntu.com/questions/408365/gnome-3-10-sharing-desktop-how-to-configure-the-security-type-for-vnc

Thanks.
