Fixed bugs (now you can run multiple background session in multiple bots), added option to count users, added option to parse markdown and html using send_message, updated documentation and decided to put the sending loop for interactive chats in the background using tmux so that if I have to update the bot interactive sessions will continue to send out messages. Also changed the file name and the location (/tmp/ of the fifos for interactive chats) and added option to broadcast messages to all users.
