Bing Maps key changes.

 * New default Bing key (Basic / Public website).
 * Write a message to the console when this default key is used.
 * Add the ability to supply a new default Bing key (and eliminate the
message) by setting a property, in addition to optionally passing it to
the constructor as before.
Consistently call the key a key.
