Omegle support and minor #! fix

Now if you type "Omegle, ...", gossbot will pose everything after "Omegle," to a random person on Omegle and then echo the response to the chat.

For example, "Omegle, what is the color of the sky?" might get you the answer "Blue" (but it will probably just be some dude asking "ASL").

Feel free to change the semantics of how the question is posed to gossbot. You might want to just have the question asked by addressing it as "gossbot", not "Omegle".
