Fixes #1970.

when clicking on a contact in roster : remove duplicate code, also open awaiting events when middle clicking
instead of always open chat

(<jid> [account]). If account is not specified,
show a combobox with active accounts

a different tab.

disconnected + fix reference before assignement TB

A friend running OpenBox on Debian had an undefined trayicons_functions symbol which prevented the trayicon from loading.  This patch fixes that.

Don't print "new_nick has joined the room" after "old_nick is now known as new_nick". Add new_nick to roster
when we receive /nick stanza.

configured print_status_in_muc

This should make tray icon transparent for non-
gnome desktops.

Sort groups in edit group dialog, even when adding one. Note that it doesn't lower groupname before sort.
Make edit group window longer but with no vscroolbar if necessary.

When in merged account mode, if we drag and drop contacts from one account to another, show drop menu,
allow to change group, inform user why creation of metacontact is not possible. Fixes #1383.

is lost ??? #1955 by j@bootlab.org

-moved popup and sound for contact in/out
-added popup for status change (always disable for the moment, will be advanced only)
Note : removed "if not gajim.awaiting_events[account].has_key(jid)" from condition for an in/out popup to be showed

print_status_in_muc is not a string which can be 'all', 'none' or 'in_and_out'(default one). version is 0.10.0.1 to update this variable.
show_status becomes print_status in server (show_status is still read for transition)
