Release 2.0.0

! Backward compatibility with old sessions file (sessions.db) is broken due to planned config variables in future. New format is:
 :sessions
   jid@server
     :login: '1234567890'

— Huge code refactoring and readability improvement
— Removed XMPP features jabber:iq:register (will now try to log in after subscription request) and jabber:iq:gateway (since it does not working on foreign servers?)
— Reworked application logic — now code in `xmppcomponent.rb` only used to XMPP jobs and `telegramclient.rb` aims Telegram.
  Because of that, commands like /login /code /password are moved out to `telegramclient.rb` and now are parts of internal command to gateway (chat id 0)
— Reworked /chat and /gateway command list — please, just send /help to gateway or any active chat.
— Improved stability (I hope so...)
— Any other small (and not only) unlisted and forgotten changes..

### Dependencies ###

* Ruby >= 1.9
* ruby-sqlite3 >= 1.3
* xmpp4r == 0.5.6
* tdlib-ruby == 2.0 with pre-compiled _libtdjson.so_
* memprof2 == 0.1.2 (optional, if running with --profiler key to detailed memory usage information)

There is pre-compiled _libtdjson.so_ for Debian Stretch x64 in repository.
For any other distro you need to manually compile [**tdlib**](https://github.com/tdlib/td) and place _libtdjson.so_ to relative **lib/** directory (or **LD_LIBRARY_PATH**).
