[Merge] lp:~michael-sheldon/content-hub/cancel-button into lp:content-hub

[Ken VanDine]

This looks good to me, however seems with the recent sdk changes the transfer hint looks a bit confusing.  It displays the white box with activity spinner, it used to just be a black overlay with spinner.  Perhaps we should put some text in there "Transfer in progress", or some variation of that.
