show notification in status bar

[ShikherVerma]

Right now the notification in the status bar does nothing on click. and any new notifications are blocked by the old notification.
What instead should be happening is that
1 on clicking the notification antaragni app should start preferably if it is a result or schedule change then the appropriate event details screen should start and if it is a notification then the app should start as normal. The later part is easy , how to do the former part will have to figured out.
2 on arrival of new notification the new notification text should get amended to the old notification msg or more than one notification should be shown.

Since I have made event details screen as a separate activity instead of a fragment so it might be easy to make it launchable with an event name, then in the EventDetailActivity can as DataProvider to give the event object for that particular event name.
