Add Audible edition of Our Man: Richard Holbrooke and the End of the American Century

[Campbell]

Please add the Audible edition of Our Man: Richard Holbrooke and the End of the American Century. The details and cover art can be found here: https://www.audible.com.au/pd/Our-Man...

Please also change the edition I have shelved to the audible one once it's created (not added again).

Lastly, please reverse the highly counterproductive ban on users adding books themselves.

Thanks.
