- user class now has priority attribut
- remove can only be done by the popup menu (BUG : when editing is canceled, iter stays editable. need gtk2.4 to coreect that)
- cleaner code

if a user log on with a resource then log off and log on with another resources, we must remove old user, what is done now

it was possible to send several time the autoaway / xa status before the first one is recieved by the server and taken into account.

- no need to store .mo files : they are now created by make

change icon in message window only if all the connexions of the user (with differents resources) are off.

it is possible to have a disconnectHandler colled during the con.connect() function if jabber server is brocken.

we can recieve presence before recieving the roster (presence from disconnected transport) so self.connexions[con] must exist for presenceCB.

bugfix : we can recieve messages from offline contacts (invisible or offline stored messages). In thoses cases do not select contact in roster.

bugfix : when a server become unavailable, self.connexions's size changed during process. Now it changes after process.
