[dcplusplus-devel] patch: save user nicks

[poy <po...@12...>]

simple patch that saves user nicks to a file called "Users.xml", and 
restores them on restart. avoids having CIDs of disconnected users displayed 
all over the UI.

the list is never purged; maybe store the time the user was last connected, 
and remove old users based on that time?
