Datasource is missing the constructor function

[michael-e]

The datasource is missing the standard constructor function:

public function __construct(&$parent, $env=NULL, $process_params=true){
    parent::__construct($parent, $env, $process_params);
    $this->_dependencies = array();
}

Without this function, the datasource will not have any dependencies, which in turn will cause the core (i.e. class.frontendpage.php) to fill the log with warnings like this:

2010/04/03 23:35:43 > WARNING: 2 - array_intersect() [<a href='function.array-intersect'>function.array-intersect</a>]: Argument #2 is not an array in file /var/www/www.example.com/symphony/lib/toolkit/class.frontendpage.php on line 427

Adding the constructor function should solve the problem.
