[PRQ#52057] Deletion Request for atd-demo

MarsSeed [1] filed a deletion request for atd-demo [2]: Broken demo game pkg from 2011. Package name is not making this easy to find. The full version of Airline Tycoon Deluxe has been re-released DRM- free to GOG.com in 2015 and includes the native Linux port. [a] Not beneficial to keep this dead demo package.
