DB Tables Optimization

Browse Source 
Reconsidered the use of MyISAM. Due to the old nature of the version of MySQL being used (5.1), the use of MyISAM on ROM-like tables makes it optimal since the table locks occurs only upon write.
Added indexes on several tables, thus improving data reading by queries.
