TODO LIST
=============
* Document code
	Very important, since now it is far more complex
  
* Clean code. Some ideas:
** Substitute bot calls with API functions (i.e. sendMessage, forwardMessage...).
   Functions are already written (not yet tested!) in shared.php
** Create a class for inline keyboard management
** Use info(), warning() and error() instead of botlog()
** Always insert "or error(... $sql->error())" when making SQL queries.

* Capabilities to send Image/Videos/Document (at the moment are blocked)

* Facebook page integration
  Make the bot publish info not only in mailing list and Telegram channel,
  but also on our Facebook page
