Subject: Implement window.alert() and its cousins for extensions. Second try,
 now with fixed observer.

BUG=12126
TEST=put a window.prompt() in a background page, a browser action, and a page action.
Make sure it gets the result back correctly. Also make sure it still works when
called from a web page.
Review URL: http://codereview.chromium.org/373006
