Release 1.2

[!] Using YAML serilaization instead of sqlite3. You may convert your SQLite db to YAML format using this:
    (echo "---"; sqlite3 users.db 'select jid,login from users'|sed "s/|/: \'/g;s/$/\'/g") > users.dat

[FIX] Fixed repllies
[UPD] Sending presence probe after disconnect received — maybe there are another XMPP resource? ☺
[UPD] When XMPP user goes online if Telegram session already established -- resync statuses with Telegram network to get all contacts online immediately
