[SVN] release 0.4.0

[SVN] all comments in code now in English; Sofia ♥ Fuck you with this barbarian language in code comments! (no, no fuck please)
[FIX] monkey-patched telethon library to fix updates receiving in some sessions (fix github issue #686; commit b20aa0ccc91b3d767c26702f3611c44772d87f5a)
[FIX] fixed "normal" quotation, such as `> text`, in previous releases it was intended to be message id to reply
[FIX] now processing bots in contact list, in roster with `b` prefix
[FIX] fixed message editing and deleting in supergroups
[FIX] now removing old telegram session from database when initiating a new one for current JID
[FIX] fixed group creating; group, supergroup, channels creating is now OK and tested
[FIX] fixed processing bot in roster; now it does not crashes gateway
[UPD] default status update interval is now 30
[UPD] slighly (and finally) changed behaviour of presences:

      `Last seen recently` = `dnd (do not disturb)`, because user that enabled this privacy settings does not want you to disturb
      `Last seen a long time ago` = `xa (extended away)`, because it is 'long' away
      'Last seen at %date%` = `away`, because user just got away

[ADD] basic interaction with bots (now only with text commands)
