renderer.php file causes two strict standards errors in Moodle 2.4 and 2.5

[drachels]

When using the current version of Hot Question in github in Moodle 2.4.3+ and Moodle 2.5.1+, with debugging set to developer, lines 122 and 131 cause a Strict Standards error.
Adding:
$formatoptions = new stdClass();
$a = new stdClass();

at about lines 110 and 111 will fix the errors.
