Update deploy hook, joomla.sql and configuration.php

Recent joomla.sql  was creating problems with access to database server,
#1130 error because it was having "create database mysql" line. As well
as it was outdated with only 34 tables, maybe it was joomla 1.5 database
dump. Joomla 2.5 has 61 tables. Also, changed table prefix for new dump
to "sfj8s_".
Merge pull request #5 from meghraj27/master

Fixed the cause of  #1130 error as well as updated it for joomla 2.5
