Quiz and Question nodes should not display their Author or Published Date by default.

Here's a patch that addresses the quiz node's install file to add a few lines that look like this:

<?php
// Default the "Show Author and Date" for quiz nodes to OFF.
$temp_array = variable_get('theme_settings', $default);
$temp_array['toggle_node_info_quiz'] = 0;
variable_set('theme_settings', $temp_array);
?>

This will reach into the theme_settings serialized array and add a zero, thus defaulting the 'show author' checkbox, found on the admin/build/theme/settings page, to default to OFF upon installation of the module. Site admins can re-enable this settings at any time in the future. This ensures that we're not stealing control of their site from them, but we default to a much prettier out-of-the-box scenario.

[a separate patch for the multichoice.module will follow. I'm not comfortable rolling patches for multiple files.]
