BrainyQuote: Prettify.
BrainyQuote: Added in @sdougbrown certified code for adding in quotes.

@chrismorast and @sdougbrown gave comments on the design of the BrainyQuotes IA. One of the changes in this one is the closing smart quote.
BrainyQuotes: Limit the output to 85 characters.

Some quotations can be very long so we want to trim those down to a few characters.
