Add option to trade names or offer another name for the listed one.

This idea should be for names on the marketplace and off the marketplace as well. (or should that be a new suggestion?) There are a bunch of names that I'd love to make an offer on, but they are not on the marketplace, and I know they are just sitting there collecting dust in someone's wallet.

Please just glance at my recent ask, secondary auction. There may be synergies in development.
