RFE: Support for actionable notifications

[GoogleCodeExporter]

Please provide any additional information below.

Just watching the Google I/O 2012 keynotes on Android JellyBean, and saw a 
feature I'd love to see supported on CN1 notifications in the future.  
Actionable Notifications allows the user to interact with the notification 
directly from the notification bar, ie. a missed call notification has a 'call 
back' action right in the notification bar.

Here's a video demonstration, at the 17m:22s mark:

We need to provide a notification API and it should include these features as 
well.

added a notification API although it's not as feature rich as described on the 
video.
