Added You are <something> pattern + more variety of responses

Added the you are <something pattern so that when the user types “You
are weird” the response is “How am I weird?”
You are <something> -> How am I <something>?

I also added more possible responses for certain keywords.

For example, if the user uses the word “ain’t”, there are different
possible responses chosen randomly.
“Watch your mouth.” or “Don’t you dare use that kind of language in
front of me!”
