 * Batch Install program this is to only be run from the command line. The web interface uses
 * a different approach to invoking the installer
 * Command line parameters:
 * -h     Database host          (default: localhost)
 * -u     Database user          (default: root)
 * -p     Database user password (default: )
 * -d     Database name          (default: gallery3)
 * -i     Database type          (default: mysqli)
 * -t     Table prefix           (default: )
 * -m     Modules to install     (default: core, user)
 * -f     Response file          (default: not used)
 *        The response file is a php file that contains the following syntax;
 *        $config[key] = value;
 *        Where key is one of "host", "user", "password", "dbname", "prefix".  Values specified
 *        on the command line will override values contained in this file
