Dangerous download dialog for linux.

BUG=11780
TEST=go to cygwin.com, click "install or update now". The download shelf should appear with a dangerous download dialog, which should animate properly and without undue jank. Clicking "cancel" should delete the item and hide the shelf (since it's the only thing in the shelf). Clicking "save" should make it become a normal download item.
