Hi Alex,

a customer of mine is paying me to do some work on X2Go Client and  
X2Go Broker.

While doing that, I noticed that the --change-broker-pass option in  
X2Go Client does not fully work together with the X2Go Session Broker.  
In fact, I could not find any implementation reference in earlier  
broker prototypes.

I thus came up with some "API" for password setting.

When the client sends the setpass task to the broker, it expects an  
answer (success or failure). I will scan for PASSWORD CHANGED: OK (or  
something else).

Please take a look at the below patch, if it breaks something for your setups.

If you have a different "API" for setpass, please let me know and I  
adapt the patch.
