Launcher - Dragging and dropping a running application in to the Trash should quit the application and (if the app is pinned to the Launcher) un-pin the application from the Launcher

Bug Description

Dragging and dropping a running application in to the Trash should quit the application and (if the app is locked to the Launcher) un-lock the application from the Launcher. If the action of closing the application triggers a warning (e.g. "this file has not been saved, are you sure you want to close", etc...) the warning dialogue should be displayed and behave as usual.

Note this bug is related to https://bugs.launchpad.net/ayatana-design/+bug/874380

Shouldn't also the trash icon change when it can accept launcher icon events?

This bug was fixed in the package unity - 5.0.0-0ubuntu1
