Subject: [PATCH 07/43] - Added drop/add primary key methods to Command.php -
 Added drop/add primary key methods to QueryBuilder.php - Added mysql specific
 dropPrimarykey method - Added sqlite specific dropPrimarykey and
 addPrimaryKey methods - Added uint testing for dropPrimarykey and
 addPrimaryKey methods - Corrected postgresql column types, by adding length
 and precision
