StuffBot 2

A joke bot that I wanted to create for the sole purpose of sending the iconic image of Robert Downey Jr. (the "I'm Stuff" one) whenever the bot detects that someone has sent the message containing the words 'I'm" and "stuff" (not case sensitive). There isn't much else to this bot, but I will be adding additional features in the near future, probably something familiar to what I have currently (message contains certain keyword(s) and the bot responds with an embed with the meme)
