Allow players to make offers in the Baazaar

Sometimes you might find an item or Aavegotchi in the Baazaar that you're interested in purchasing, but aren't comfortable with the price specified. Currently, there isn't a clear cut way to contact the owner to try to see if they would accept a lower (reasonable) price.

This proposal is to allow players to offer a lower price than what is specified in the Baazaar and the person who listed it gets a notification of the offer. They can choose to accept or reject the offer.
