Added the basic insert query for the newsfeed table.

TODO: Add a timestamp column and make sure that it has the default value
of the current timestamp.
Added the new table that will have the data regarding the latest activity and will
enable the display of the newsfeed.
[completed] The News Feed.

Now the feed is properly displayed, and it is arranged so that the latest event is on
top of the list. The userid that related to a newsiteam can be integrated.
Added a news feed link in the header file.
[completed] News feed display with another column called userid.

everytime a record is entered into the newsfeed the userid that is initiating
this change is also stored.

Later, maybe, we can add the activity page of each member which can be seen by every coordinator, or someone higher up in the heriarchy.
Changed the erp.sql file. This file now conatins the new table and also the foreign key relationships
that are required for the latest activity table.
