###What happened:
- Adding custom finders with an array of $options does not work


###What was expected:
- Call to Model::find('custom', array(/* something */)); borks
- Resulting query does not include $options

{{{
// Finder options
$options = array(
    'fields' => array('name', 'created'),
    'conditions' => array(
        'created' => array(
            '>=' => date('Y-m-d', strtotime('7 days ago'))
        )
    )
);

Companies::find('all', $options);
// SELECT name, created FROM `companies` AS `Companies` WHERE (`created` >= '2011-05-16');

Companies::finder('lastWeek', $options);
// SELECT * FROM `companies` AS `Companies`; 
}}}


#### Changes

Added some code to Model::find()
