Added Not Found Message and fixed help

[coodos]

The bot did not respond to messages containing the word help earlier and did not return a message when it could not find documentation for a said argument. This PR intends those two things.

Furthermore I have also added a requirements.txt file to make it as easy as
pip3 install -r requirements.txt for someone to install dependencies :)

• Added requirements.txt
• Added not found message
• Made the bot respond to a message containing the word help with the help message

Just one last question: What if I just ping the bot? It would print the not found message. Maybe that should be checked and print the help message?

I forgot about that :P
I would add it soon
