DART Taxonomy module 'Default taxonomy value' not sticky on 'Global DART Settings' admin form

The default taxonomy setting does not stick in the config drop list after the setting has been updated, the default variable_get value argument - '_dart_taxonomy_callback_tid' - is always displayed, though the saved value is set properly in the variables table. This is simply due to a minor typo in the in the name value in the variable_get() call for the #default_value :

line 72 (dart_taxonomy.module)
$form['taxonomy_settings']['dart_taxonomy_default_callback'] = array(
'#type' => 'select',
'#options' => _dart_taxonomy_callbacks(),
'#title' => t('Default taxonomy value'),
'#default_value' => variable_get('dart_taxonomy_default_value_callback', '_dart_taxonomy_callback_tid'),
'#required' => TRUE,
'#description' => t('How should the taxonomy terms be displayed when included in a DART tag.'),
);
break;

'dart_taxonomy_default_value_callback' should be 'dart_taxonomy_default_callback'

I would post this as a patch, but I've never posted a patch before and am not sure how to roll one out (I am behind on a deadline tonight, so I don't have time to mess with it right now :-)
