[/trunk] Changeset 51 by mikael Work on libjabber integration. This is a big patch... * Remove socket.[ch] server.[ch] We have now fully switched to libjabber. * Roster is fetched, and buddies are added to the buddylist * Can send/receive messages using libjabber * Presence messages are handled. I have added statuses, as there only were online / offline statuses. * Use halfdelay to have a non-blocking getch(). And use a timeout in jb_main(). * Use utf8_{encode,decode}
