`preloadSubsectionEntries` assumes `$parents` will be an array

Resulting in:

Invalid argument supplied for foreach()

An error occurred in /Users/brendanabbott/Sites/symphony-2.local/extensions/subsectionmanager/extension.driver.php around line 337

333:         public static function preloadSubsectionEntries($parents) {
334:
335:             // Get parent data
336:             $fields = array();
337:             foreach($parents as $entry) {

340:                 // Get relation id
341:                 foreach($data as $field => $settings) { 

I'd recommend setting the function to (array $parents = array()) or checking that $parents is actually an array before running foreach
