bookmarks in menu isn't updated
if you are in a gc room and use use the actions menu to bookmark it (or chose bookmark from tab context menu), the bookmark doesn't show in the "join groupchat" menu before you exit gajim and start it again. but it is in the "manage bookmarks" window, so it is added. if you add a bookmark in the "manage bookmarks" window, the menu isn't updated aswell.
the menu should be updated when you add a bookmark.
