----------------------------------

    Attachment: mapred-1027-v1.2.patch

Attaching a patch that implements the proposed design. Testing in progress. This patch does the following
- Adds an announcement block on jobtracker webui
- allows loading new announcements via mradmin -loadAnnouncements
- distinguishes between old and new announcements
- allows capping the total announcements (default 10)

Announcements are expected in the format
{code}
<int id> <message>
example :
2 New announcement added
1 Test announcement
{code}
where the id is used to distinguish old and new announcements. 

> jobtracker.jsp can have an html text block for announcements by admins.

> jobtracker.jsp is the first page for users of Map/Reduce clusters and can be used for sending information across to all users. It will be useful to have a text block on this page where administrators can put any latest notices/announcements time to time.
