commited changes in Notification module

1)- Notification will go to only owner i.e Writer of Status,
2)- To achieve that in controller we are taking mail_Id of owner of status & comparing that with commenter mail_Id,
3)- If they 2 find equal then notification will not going,
4)- If they 2 find different then only notification will go to owner of Status.
5)- Refactoring of POST() in NotificationController, POST() is is not needed, it's fine to go with GET().
6)- Now From Notification.jsp user will jump to correct comment on home; recoved error in JavaScript.
7)- in all jsp pages Removed unNecessery Form action with post() to get All notifications; now we are going with simple href attribute not with post().
