Forward messages from a name to saved messages without marking message as seen in Telegram

forwarder.py

# After running the script in logging in to your account, send "forward_unseen:mister_x:10" to your saved messages,
# the bot will then forward 10 last messages of the first user with name mister_x to your saved messages.
# This way you can check what people have sent you without them knowing you did.
